I have an application where each user can have several email id's.(Assume these emails are stored in a list)
Associated with each email, I have a fixed number of settings, which I can retrieve/save by a:
"user.email.settings.setting1 = 'value' "
I want the user to be able to change the settings for all the emails simultaneously and then submit all the changes, as shown in the following figure :

How can I achieve this in Django?
Should I have separate forms/views or can I implement this in a single go?

In views, I have a function defined which is executed when the user submits the form online. After the form submission there are some database transactions that I perform and then based on the existing data in the database API's are triggered:
triggerapi():
execute API to send Email to the user and the administrator about
the submitted form
def databasetransactions():
check the data in the submitted form with the data in DB
if the last data submitted by the user is before 10 mins or more:
triggerapi()
def formsubmitted(request):
save the user input in variables
Databasetransactions()
save the data from the submitted form in the DB
In the above case, the user clicks on submit button 2 times in less than 5 milliseond duration. So 2 parallel data starts to process and both trigger Email which is not the desired behavior.
Is there a way to avoid this ? So that for a user session, the application should only accept the data once all the older data processing is completed ?
Since we are talking in pseudo-code, one way could be to use a singleton pattern for triggerapi() and return Not Allowed in case it is already istantiated.
There are multiple ways to solve this issue.
One of them would be to create a new session variable
request.session['activetransaction'] = True
This would however require you to pass request, unless it is already passed and we got a changed code portion. You can also add an instance/ class flag for it in the same way and check with it.
Another way, which might work if you need those submissions handled after the previous one, you can always add a while request.session['activetransaction']: and do the handling afterwards.
def formsubmitted(request):
if 'activetransaction' not in request.session or not request.session['activetransaction']:
request.session['activetransaction'] = True
# save the user input in variables
Databasetransactions()
# save the data from the submitted form in the DB
request.session['activetransaction'] = False

I'm making a system to track entries to a sports day event and I can get the data from the form to the Python back-end but I don't know how to get the data for the event entries to the back-end too.
I have a form I've already created using Flask and WTForms and I can submit all the data relating to the user but since they can enter from just a single event all the way up to every event they are able to enter the form will have a variable number of selection fields, I want to pack this data from the selection fields into a JSON string and then have Python process it since that is very easy. My only problem is, how can I get this data into a JSON string then send it in a single request to the back-end with the other data, like first name, last name etc.
Screenshot showing the user interface of the form
from flask import jsonify
#app.route('/selects')
def selects():
selects = ['one', 'two']
return jsonify(selects)
I have the same question and found answer in this tutorial. If you already use WTForm to make the form, the content can be access via methods. This should be straightforward. https://pythonspot.com/category/pro/web/page/2/
I am working with a Delayed Job that, after its completion, sends an email to the admin user that requested it. So, to do this, I need to know who is the admin user that launched it inside the Spree::Order model.
I've tried with try_spree_current_user and spree_current_user but they don't work returning:
NameError (undefined local variable or method `try_spree_current_user' for #<Spree::Order:0x007f93811d7240>):
app/models/spree/order_decorator.rb:30:in `after_cancel'
app/controllers/spree/admin/orders_controller_decorator.rb:4:in `cancel'
Some how you need to make sure that an admin can launch the order:
# Is this user an admin
if spree_current_user.admin?
# Do some delayed job
# send the email
# because spree_current_user.id is the one that sends it
else
flash[:error] = "You need to be an admin to do this."
redirect_back_or_default(spree.root_path)
end
The above should do what you want to do. You need to test if the current user is an admin then do what he/she needs to do.
I'm sure you meant the OrdersController? Not model.
How to verify email through link.
I have user edit profile and it is showing user email.I want to give one link to verify email.I do not what to do.
Add one column to your
User Model : email_verification and by default set to zero (0).
Then using persistence_token create a URL and sent to that specific email address. If you dnt have persistence_token as column in your User model then you can add custom column of your choice like verify_email_token as column name and stored 50 random string.
Using
o = [('a'..'z'),('A'..'Z'),('0'..'9')].map{|i| i.to_a}.flatten
string = (0...50).map{ o[rand(o.length)] }.join
URL example :
http://www.yoursitename.com/VerifyEmailAddress/?token=persistence_token ;
When user click on that link, internally call function like VerifyEmailAddress and in that method update email_verification column by one (1).
I am working on a web app, in Django, which lets user tell their favourite movies. For the input I want to provide users a textbox with autocomplete enabled.
The list of all movies ever made is very big (18 MB) thus autocomplete has to be enabled using remote source.
To add to this, I have the constraint that I can not use a database. (Because my app is hosted on heroku and to store such data in database would cost a lot)
Right now, I have the list of all movies stored in a .py file, and I import it into my views.py. The view which handles the ajax request from autocomplete iterates over each movie in this list to filter based on the query term and returns the filtered list.
-movies.py
all_movies = [list of all movies' titles] # > 1M string elements
-views.py (handle_autocomplete() gets called whenever user changes the input in the textbox on web app)
import movies
def handle_autocomplete(request):
data = request.GET['term']
my_list = [title for title in movies.all_movies if data in title]
return HttpResponse(simplejson.dumps(my_list))
What are the disadvantages of this approach and how can I improve upon it?
Are there any libraries/ django apps which handle remote-source autocomplete ?
