Getting User Information from Django Python Social Auth in the view
First time working with python-social-auth and Django but having trouble figuring out exactly how much information about the user's social account is available to me. When I access the extra_data of the UserSocialAuth object I can get the uid, and the access_token. To get additional details am I to feed those through the social company's (ex facebook) API? I can see that for some social auths like facebook Django's user object is magically populated with the first and last names from the social profile, but for others like LinkedIn that doesn't work. How do i find out which information is available for each social auth without manually probing each one? I'm just trying to get as much "Profile" data from the user and am worried going through the API is the "long way" of achieving this. I have actually read through the documentation but it may be too advanced for me; im not sure how to use the data that is acquired by the pipeline from the view. I'm not even sure if that sentence makes sense! -

Django share requests.session() between views
I make 2-3 calls to an API URL per view and using requests.session() cuts down the connection time by a significant amount. Is there a way to keep the session open between views to avoid the initial setup time? -

Cronned Django command output not posted in tee from bash script
I'm trying to have a bash script that controled by cron to be ran every day and I would like to grep some lines from the python (Django) output and post it with slacktee to my slack channel. But I am only catching some warnings from the script, not my own prints (something to do with std::out and std::err)? But I can't seem to be able to debug it. #!/bin/bash printf "\nStarting the products update command\n" DATE=`date +%Y-%m-%d` source mypath/bin/activate cd some/path/_production/_server ./manage.py nn_products_update > logs/product_updates.log tail --lines=1000 logs/product_updates.log | grep INFO | grep $DATE So for each day, I'm trying to grep messages like these: [INFO][NEURAL_RECO_UPDATE][2017-08-28 22:15:04] Products update... But it doesn't get printed in the tee channel. Moreover, the file gets overwritten everyday and not appended - how to change that, please? The tail command works ok when ran in the shell by itself. How is it possible? (sorry for asking two, but I believe they are somehow related, just cant find an answer) This is just in case the cron entry. 20 20 * * * /bin/bash /path/to/server/_production/bin/runReco.sh 2>&1 | slacktee.sh -c 'my_watch' Many thanks -

Converting Tuple inside of an array into a dictionary in Python
I have been trying to solve this problem but I cannot get it right :( I am querying mySQL database in Django, and my results comes back as a tuple inside of an array. Please see dummy data below; query_results = [ (500, datetime.date(2017, 1, 1)), (302, datetime.date(2017, 1, 2)), (550, datetime.date(2017, 1, 3)), (180, datetime.date(2017, 1, 4)), (645, datetime.date(2017, 1, 5)), (465, datetime.date(2017, 1,6)) ] 500, 302, 550 etc... are my records.

Can anyone please give me some advise on how to append these into something like this: myDict = { "record": "", "date": "" } All help is greatly appreciated! -

How to assert django uses certain template in pytest
In the unittest style, I can test that a page uses a particular template by calling assertTemplateUsed.

User.objects.create() does nothing. (Django)
I have a view that should run User.objects.create() for the user registration. User.objects.create(name="request.POST['name']", username="request.POST['username']", password="request.POST['password']") It obviously passes the conditionals into this code because it runs the redirect I put after it.

django multi-tenancy and wildcard subdomains
I want to offer client.domain.com for every client on the site. In practice, client.domain.com is equivalent to www.domain.com/client/ (which I know how to handle in urls but isn't what I want). Can I use django-subdomains to allow this sort of wildcarding without defining SUBDOMAIN_URLCONFS since I don't want to try and enumerate for all clients. I'm currently using Apache. I don't want to create a new virtual host for each client as well. Is there a generic way to make client.mydomain.com work? Appreciate all pointers to executing #1 and #2. Thanks. -
How to reuse a Django template?
Currently, I have almost two exact same templates and they use the same Django form, but there is only 1 parameter that changes in these two forms which is the action method, that is, Django form class DropDownMenu(forms.Form): week = forms.ChoiceField(choices=[(x,x) for x in range(1,53)] year = forms.ChoiceField(choices=[(x,x) for x in range(2015,2030)] template 1 <form id="search_dates" method="POST" action="/tickets_per_day/"> <div class="row"> <div style="display:inline-block"> <h6>Select year</h6> <select name="select_year"> <option value={{form.year}}></option> </select> </div> <button type="submit">Search</button> </div> </form> template 2 <form id="search_dates" method="POST" action="/quantitative_analysis/"> <div class="row"> <div style="display:inline-block"> <h6>Select year</h6> <select name="select_year"> <option value={{form.year}}></option> </select> </div> <button type="submit">Search</button> </div> </form> The only thing that varies is the action method, so I would like to know if it is possible to re-use one template that varies only in the action method. If it is possible, can you help me with the code? I checked this question django - how to reuse a template for nearly identical models? but I am not using any model here with my templates. -
