00:00:01,100 --> 00:00:08,030
Hello, friends, in this video, we shall see how to use the flask male extension.

2
00:00:15,570 --> 00:00:24,060
EMAC General-Purpose Web application, it is often required that the application must have an email

3
00:00:24,270 --> 00:00:25,050
sending.

4
00:00:25,990 --> 00:00:26,570
Facility.

5
00:00:27,010 --> 00:00:33,940
So this email support feature can be activated in your application by using the flask mail extension.

6
00:00:36,090 --> 00:00:42,810
Flask mail extension can be installed in the flask and worn by two different.

7
00:00:43,200 --> 00:00:47,590
This one is a straightforward utility can be used.

8
00:00:47,610 --> 00:00:49,950
You can pip install flask M..

9
00:00:51,600 --> 00:00:58,460
So because the last male extension is holstered on the pipeline, that is the Python package index,

10
00:00:59,370 --> 00:01:04,710
it can be easily installed by using the utility, but in case in some.

11
00:01:05,820 --> 00:01:11,700
Operating system platforms are in some environments, the utility is.

12
00:01:12,700 --> 00:01:20,920
Not able to install it, then the better the other alternative is to download the latest version of

13
00:01:20,920 --> 00:01:29,890
this e-mail from this git repository and then install by saying set up what you are installed.

14
00:01:30,790 --> 00:01:36,820
So this is the installation from code and this is the installation by the help of the utility, any

15
00:01:36,820 --> 00:01:38,170
of which can be used.

16
00:01:42,240 --> 00:01:50,940
After the flask extension has been installed or has been incorporated into a flask environment, then

17
00:01:51,570 --> 00:01:58,320
Quada for its use to be done with the help of the inside of the flask application, the flask application

18
00:01:58,320 --> 00:01:59,820
must be properly configured.

19
00:02:01,140 --> 00:02:07,800
And these are the different configuration settings that you may have to provide in your application.

20
00:02:08,670 --> 00:02:16,890
For example, you have to provide or specify the mail server setting mail server is about the name or

21
00:02:16,890 --> 00:02:18,750
IP address of your e-mail server.

22
00:02:19,710 --> 00:02:27,300
That you must specify in this configuration, mainboard board, the server and the port number have

23
00:02:27,300 --> 00:02:28,440
to be specified.

24
00:02:29,380 --> 00:02:38,300
On Witchboard, the email server is going to keep on listening the requests use less and use SSL.

25
00:02:38,330 --> 00:02:45,880
These are the two settings configurations which will either enable or disable the transport security

26
00:02:45,880 --> 00:02:50,650
layer or SSL encryption support can be enabled or disable.

27
00:02:50,650 --> 00:02:54,630
Both of them are boolean function boolean settings.

28
00:02:55,030 --> 00:02:57,820
So is the debug is also a boolean setting.

29
00:02:57,820 --> 00:03:00,700
It can be enabled or disable.

30
00:03:00,700 --> 00:03:03,940
It will either enable the debug support or disable.

31
00:03:04,600 --> 00:03:04,980
Right.

32
00:03:05,500 --> 00:03:08,650
Then these two settings are the most important ones.

33
00:03:09,820 --> 00:03:14,840
You have to first set up the username and password of the sender.

34
00:03:14,860 --> 00:03:18,340
So that means basically you're to log into your email server.

35
00:03:19,210 --> 00:03:22,410
These two are username and password settings.

36
00:03:23,320 --> 00:03:25,780
You can also specify the default sender.

37
00:03:28,310 --> 00:03:34,820
You can set the maximum image that can be sent at one through one round of application.

38
00:03:36,690 --> 00:03:45,930
Melissa precent is a barometer, is an attribute if the standing is suppressed, if the app testing

39
00:03:45,930 --> 00:03:46,830
is to prove.

40
00:03:48,220 --> 00:03:56,740
And lastly, there is a male askey attachment setting, if it is true, then attach the filenames are

41
00:03:56,740 --> 00:03:58,180
converted into an ASCII.

42
00:03:59,290 --> 00:04:07,930
These are some of the important attributes or settings that you have to provide or properly set in the

43
00:04:08,260 --> 00:04:10,360
application configuration settings.

44
00:04:14,800 --> 00:04:17,960
The plastic extension has two important classes.

45
00:04:18,670 --> 00:04:21,520
One is the middle class and the other is a message class.

46
00:04:22,600 --> 00:04:26,380
The middle class manages the email messaging requirements.

47
00:04:28,210 --> 00:04:37,780
The glass constructor takes a very simple and straightforward form flask, male or male, in the bracket,

48
00:04:37,810 --> 00:04:47,080
the name of the application object, and these three very important functions associated in the class

49
00:04:47,260 --> 00:04:48,490
are frequently used.

50
00:04:48,850 --> 00:04:53,950
Sand is a function of obviously a very important function because it sends the content of the message

51
00:04:53,950 --> 00:04:55,060
glass object.

52
00:04:56,590 --> 00:05:04,150
Connect, it opens the connection with the video, we must provide the host name and airport name in

53
00:05:04,150 --> 00:05:10,900
the configuration settings using those settings the server will be connected to with the help of the

54
00:05:10,900 --> 00:05:11,610
connect function.

55
00:05:11,980 --> 00:05:12,880
And then there is it.

56
00:05:12,880 --> 00:05:15,640
Send message functions, sends the message.

57
00:05:16,360 --> 00:05:21,750
So these three are the important matters that are defined in the middle class.

58
00:05:22,420 --> 00:05:23,650
This is about the middle class.

59
00:05:23,890 --> 00:05:28,800
The other class that is present in the extension is called the message class.

60
00:05:29,770 --> 00:05:37,630
This message class controls are embedded encapsulates is the proper word and e-mail message.

61
00:05:39,310 --> 00:05:42,790
The message glass constrictor has several parents.

62
00:05:43,790 --> 00:05:45,710
This is a list of the different parameters.

63
00:05:47,050 --> 00:05:56,910
Which is in the name of the class subject recipients, one of the many recipients, maybe their body,

64
00:05:56,920 --> 00:06:06,790
the actual text of message as HTML sender is, of course, provided the information of the sender is

65
00:06:06,970 --> 00:06:08,980
already provided in the application settings.

66
00:06:10,270 --> 00:06:11,650
Cissie NBCC.

67
00:06:12,760 --> 00:06:21,100
They reply to their characters, characters, set Heather's meal options, recipient options, etc.,

68
00:06:21,100 --> 00:06:24,820
etc., these are all the different parameters that you can provide.

69
00:06:25,390 --> 00:06:27,970
Some of them, or many of them, rather, are optional.

70
00:06:27,970 --> 00:06:32,380
For example, is optional mail options.

71
00:06:32,560 --> 00:06:36,550
Recipient options can be optionally you are ignored like that.

72
00:06:38,160 --> 00:06:43,490
What are the different and important message class matters, one is at that.

73
00:06:44,820 --> 00:06:52,380
If you want to send a certain resource as an attachment to the mail, as an attachment to the message,

74
00:06:52,680 --> 00:06:56,710
this method takes following parameters which file name to be attached.

75
00:06:57,060 --> 00:07:05,580
What is the content type, whether it is a text file or image file or what type of file this data and

76
00:07:05,580 --> 00:07:09,190
disposition, the content, disposition, etc., if there is any.

77
00:07:09,650 --> 00:07:14,850
So these are all the different parameters to the attach function and our recipient is another matter

78
00:07:15,240 --> 00:07:17,880
and another recipient of the message.

79
00:07:18,360 --> 00:07:18,840
So.

80
00:07:20,130 --> 00:07:26,340
In order to board, the classes are very important for performing the male sending activity, so therefore

81
00:07:26,340 --> 00:07:28,180
both these classes must be important.

82
00:07:28,770 --> 00:07:36,420
The last male import male and this is a very mandatory statement that you must write.

83
00:07:40,210 --> 00:07:40,660
So.

84
00:07:41,930 --> 00:07:53,180
Using this in our discussion as a basis, we shall now see how to send the email using the Gmail, Gmail

85
00:07:53,180 --> 00:08:00,340
is a very popular e-mail that we value you, all of you must be doing using that Gmail, Gmail, SMTP

86
00:08:00,350 --> 00:08:00,760
server.

87
00:08:00,770 --> 00:08:08,990
We will use as a as our server and then try to send email to our by chance application.

88
00:08:09,710 --> 00:08:11,170
So this is the application setting.

89
00:08:12,200 --> 00:08:15,980
Most importantly at dot config mail server setting.

90
00:08:15,980 --> 00:08:21,680
I'm using the name of the assembly server of the Gmail service.

91
00:08:21,980 --> 00:08:23,990
So SBP Gmail dot com.

92
00:08:24,890 --> 00:08:28,370
The recommended number by Gmail is four six five.

93
00:08:31,330 --> 00:08:32,590
Username and password.

94
00:08:33,940 --> 00:08:41,710
You must be a user of G.M., of course, in order to use email, SMTP password cannot be rebuilt, so

95
00:08:41,710 --> 00:08:50,380
therefore I am putting starts beardless and assesses these two parameters to force us to do this.

96
00:08:50,380 --> 00:08:59,760
Is the configuration very important, that basic activity that you must perform inside the application

97
00:08:59,770 --> 00:09:02,090
would first create the application.

98
00:09:02,140 --> 00:09:06,640
The object of the middle class, then create the object of the message class.

99
00:09:08,220 --> 00:09:15,120
By giving the parameters that are mandatory, like, for example, the message center and disappears.

100
00:09:16,050 --> 00:09:20,560
Rest of the parameters that we saw in the earlier slide are all optional.

101
00:09:21,910 --> 00:09:25,630
OK, and then same message, not body is equal to the lower floors.

102
00:09:25,660 --> 00:09:30,510
The message sent from some such thing will be said as the body of the message.

103
00:09:30,820 --> 00:09:32,790
And then this it mailed or said.

104
00:09:34,150 --> 00:09:42,640
OK, so this is the brief gist of all the activities that you have to incorporate in your

105
00:09:45,310 --> 00:09:49,570
training program using a SMTP server of the JEIMY.

106
00:09:50,410 --> 00:09:53,180
Now, incidentally, one more precaution has to be taken.

107
00:09:54,100 --> 00:09:54,760
What is that?

108
00:09:55,330 --> 00:10:01,840
Since you are using the Gmail service, are Gmail servers, SFP service?

109
00:10:02,260 --> 00:10:06,490
Gmail does not allow normally the.

110
00:10:07,860 --> 00:10:12,370
Males to be sent by a third party in a product.

111
00:10:13,140 --> 00:10:21,390
So therefore, when you are trying to send or use the same server to our third to our total program

112
00:10:21,390 --> 00:10:24,960
as a third party program for G.M., so therefore it will block it.

113
00:10:26,700 --> 00:10:34,020
So therefore, in order to let G.M. allow senators to send a message through our application, you will

114
00:10:34,020 --> 00:10:40,760
have to perform a slight, you know, setting to our Gmail account settings.

115
00:10:40,950 --> 00:10:41,720
And what is that?

116
00:10:42,150 --> 00:10:49,050
Go to this particular you are in Google dot com settings, security, less secure apps.

117
00:10:50,290 --> 00:10:53,170
So the less secure apps are normally set to.

118
00:10:54,450 --> 00:11:03,330
If it doesn't allow the less secure apps to be used to enable that support, then only this program

119
00:11:03,330 --> 00:11:08,340
will be able to send the message to the recipient that we have mentioned.

120
00:11:08,760 --> 00:11:20,400
So this is a very useful feature of last application by which you can either email support your application

121
00:11:20,820 --> 00:11:28,680
and especially this Gmail SMTP Gmail service that is that I'm demonstrating to you.

122
00:11:28,920 --> 00:11:37,200
I will now actually do this exercise in front of you, write a program, perform the settings, change

123
00:11:37,200 --> 00:11:46,740
the secure application settings, and then send the mail through the application and check in the Gmail

124
00:11:46,740 --> 00:11:50,160
account, go in the G.M. account, see whether the mail has been delivered or not.

125
00:11:50,430 --> 00:11:53,490
All this I will do as an exercise in front of you.

126
00:11:54,570 --> 00:12:01,770
So first of all, we have to verify whether the flask mail extension has been properly installed in

127
00:12:01,770 --> 00:12:04,630
our working class environment or not.

128
00:12:05,220 --> 00:12:06,330
So I have already.

129
00:12:07,300 --> 00:12:09,010
Started our activity, activated the.

130
00:12:10,020 --> 00:12:11,220
Virtual environment.

131
00:12:12,200 --> 00:12:12,740
And.

132
00:12:13,860 --> 00:12:22,040
Now, inside this, I will have to see whether this flask, male extension has been installed or not,

133
00:12:22,440 --> 00:12:28,080
how to verify that, just try to reinstall installed again by using the pipe.

134
00:12:28,530 --> 00:12:30,660
If if it is not there, it will be installed.

135
00:12:30,660 --> 00:12:32,930
Otherwise, it will say it will be all it is already present.

136
00:12:32,980 --> 00:12:33,690
So let us see.

137
00:12:34,870 --> 00:12:35,770
Uh.

138
00:12:36,640 --> 00:12:39,490
It is available in the.

139
00:12:39,850 --> 00:12:42,850
Utility is available in scripts folder.

140
00:12:54,030 --> 00:12:56,430
Flask is the name of the extension.

141
00:13:00,080 --> 00:13:02,970
So the requirement is already fulfilled or satisfied.

142
00:13:02,990 --> 00:13:05,240
That means the last mile extension is.

143
00:13:06,240 --> 00:13:06,840
Instore.

144
00:13:07,740 --> 00:13:13,380
Another way of verification, verification or verifying it is that start the Python interpreter.

145
00:13:16,800 --> 00:13:17,820
And Chambord.

146
00:13:22,520 --> 00:13:25,420
If it is able to import, then that means it is installed.

147
00:13:31,440 --> 00:13:37,400
So that means blackmail is properly installed in this in this virtual environment.

148
00:13:38,900 --> 00:13:41,390
And now this is the classic application called.

149
00:13:42,970 --> 00:13:49,360
In the beginning, you have to import the glass from the flask module, also important mail and message

150
00:13:49,360 --> 00:13:50,320
glasses from the.

151
00:13:51,660 --> 00:13:54,630
Extension that we just now install flask male.

152
00:13:56,350 --> 00:13:57,910
Set up the application object.

153
00:13:59,040 --> 00:14:00,540
Applicable to flask.

154
00:14:01,690 --> 00:14:06,550
Double underscored name, this ape object is the argument.

155
00:14:08,400 --> 00:14:13,560
To the middle class constructor's, this is a male object object of the middle class.

156
00:14:15,150 --> 00:14:22,560
Then this is necessary to do certain configuration settings to your application class by.

157
00:14:23,660 --> 00:14:26,160
Specifying the mail server.

158
00:14:26,600 --> 00:14:30,980
Here we are going to use the SMTP server of the G Mail.

159
00:14:32,120 --> 00:14:40,130
Service, so the name of the S&P, Sahuarita Centipede or Gmail dot com, the recommended port number

160
00:14:40,130 --> 00:14:41,070
is 465.

161
00:14:42,260 --> 00:14:48,830
These are the login credentials, the username and password, and these are the security settings.

162
00:14:49,280 --> 00:14:51,650
I am setting Gmail use Steeles.

163
00:14:52,560 --> 00:14:58,050
Parameter of the configuration dot com equal to false, but SSL is equal to two.

164
00:14:58,900 --> 00:14:59,740
So these are all.

165
00:15:00,790 --> 00:15:03,790
The configuration settings that you must enable.

166
00:15:05,620 --> 00:15:11,320
And now to this route, you are in the index function that is mapped.

167
00:15:12,840 --> 00:15:19,440
Inside, which what is happening, I am setting up a message glass object, and it takes three.

168
00:15:21,390 --> 00:15:28,980
Mandatory arguments, the subject, the sender and the recipient, the sender and discipline it is.

169
00:15:29,930 --> 00:15:35,330
And then the body attribute of this message object, this is the.

170
00:15:36,290 --> 00:15:37,670
Text that you want to.

171
00:15:38,960 --> 00:15:46,250
Send us an e-mail and then you just send a matter of the middle class, the matter will be sent as the

172
00:15:46,250 --> 00:15:47,210
message will be sent.

173
00:15:48,640 --> 00:15:51,190
OK, so this is the application called.

174
00:15:52,240 --> 00:15:59,710
But before running the Python application code, the flask application called you to do one more sting

175
00:15:59,950 --> 00:16:05,050
operation, go to this, you are ill after logging into your.

176
00:16:06,550 --> 00:16:14,440
Gmail account open, Google dot com settings, security and less secure apps and ensure that access

177
00:16:14,440 --> 00:16:19,420
for less secure apps is turned on by the authorities of.

178
00:16:20,930 --> 00:16:30,520
Because the G mail service or the e-mail server does not allow mail to be sent by any third party applications,

179
00:16:31,130 --> 00:16:35,630
now that our application, our application will not be.

180
00:16:36,490 --> 00:16:42,670
You're not allowed to send the mail on behalf of the Gmail service, so therefore in order to let the

181
00:16:42,670 --> 00:16:43,960
Gmail allow that.

182
00:16:46,130 --> 00:16:56,330
Turn this thing on access for less secure apps, turn it on, so that is very essential for the successful

183
00:16:56,330 --> 00:16:57,360
execution of your.

184
00:16:58,670 --> 00:17:00,200
Now, coming back to the.

185
00:17:01,710 --> 00:17:07,110
Virtual Environment Command prompt now executed that this mailed by.

186
00:17:08,090 --> 00:17:15,080
But on Milhaud, before we start the server, so the server is starting right now with it, go in the

187
00:17:15,080 --> 00:17:16,310
browser and visit this.

188
00:17:16,310 --> 00:17:18,520
You are in localhost 5000 slash.

189
00:17:19,490 --> 00:17:27,580
So I open the browser and, you know, given the you are a localhost 5000 slash.

190
00:17:28,890 --> 00:17:36,960
As soon as I press enter the message on my brother's messages sent through in order to verify that the

191
00:17:36,960 --> 00:17:39,630
messages sent and go in my inbox.

192
00:17:41,210 --> 00:17:44,200
And there you see the message, hello.

193
00:17:44,480 --> 00:17:51,500
It was the subject of the message, hello, flask, this message is sent from the last was my body of

194
00:17:51,500 --> 00:17:51,960
the message.

195
00:17:52,250 --> 00:17:57,680
So that is all you can use this as SMTP server of G.M..

196
00:17:58,820 --> 00:18:03,660
To send an e-mail message through our flask application.

197
00:18:03,710 --> 00:18:06,380
So this was a demonstration of the intent exercise.
