My Django Web gets empty values when I try to use UpdateView to edit data
I am trying to use an Edit button in my website to edit items using UpdateView. The problem is, that when I click edit the forms are staying blank without the previous data data. Under forms I have post.id that I supposed to give him so forms will know which form to get his data... but it doesn't work..

Import external react component from CDN (React Bootstrap Slider)
I have a Django project and I want to use React on it. I have already created my own components and this works, but I dont know how to import third-party components from CDN. To do this, I did: Import React (develop or production version) in the base template: <!-- baseTemplate.html --> {# ReactJs#} <script src="https://unpkg.com/react@16/umd/react.development.js"></script> <script src="https://unpkg.com/react-dom@16/umd/react-dom.development.js"></script> <script src="https://unpkg.com/babel-standalone@6.15.0/babel.min.js"></script> Also import the file where I create my components <!-- baseTemplate.html --> <script src="/one_directory/my_react.jsx" type="text/babel"></script> and create the tag where it will be rendered. <!-- template.html --> <div id="container"></div> And finally render my React components: <!-- my_react.jsx --> ReactDOM.render( <App />, document.getElementById('container') ); This works correctly :) Now, I want to import a third-party component (specifically, it's React Bootstrap Slider) from CDN, but I dont know how. Maybe this is not possible, I dont know. How could I do it? Thank you very much :] -
the miss "meida" path in django-oscar image URL
I m trying django-oscar to build an e-commerce website. I have deployed django-oscar on Heroku (with Amazon S3 as static and media file bucket), the issue is When I try to add a photo for a product on dashboard, The system returns the correct working URL https://s3.amazonaws.com/mybucket/media/cache/XXX/YYY/ZZZ.jpg that works on first page view request. Reload the page. The system returns broken URL: https://s3.amazonaws.com/mybucket/cache/XXX/YYY/ZZZ.jpg (missing 'media' path) any idea about this miss "media"? -
python - mock, patch, start and return_value
When using mock patcher with start() (and stop() later on) - does it matter when I add the return_value? For example - is there a difference between - cls._dm_delete_attachment_patcher = mock.patch.object(DmService, 'delete_attachment') cls._dm_delete_attachment_patcher.return_value = 'some_deleted_attachment_urn' cls._dm_delete_attachment_start = cls._dm_delete_attachment_patcher.start() and - cls._dm_delete_attachment_patcher = mock.patch.object(DmService, 'delete_attachment') cls._dm_delete_attachment_start = cls._dm_delete_attachment_patcher.start() cls._dm_delete_attachment_start.return_value = 'some_deleted_attachment_urn' or maybe it should be - cls._dm_delete_attachment_patcher = mock.patch.object(DmService, 'delete_attachment') cls._dm_delete_attachment_patcher.return_value = 'some_deleted_attachment_urn' cls._dm_delete_attachment_start = cls._dm_delete_attachment_patcher.start() cls._dm_delete_attachment_start.return_value = 'some_deleted_attachment_urn' In my test, seems like the first option failed, and the third did the work. I'm not sure why. -

Why python manage.py collectstatic do not copy files to correct location?
The problem I am facing is that my Django project can't find static files. I was struggling with this issue for quite a while hence, now I figured where the problem is however, I have no idea how to fix it.

including shipping in django e-commerce application
I have a django e-commerce application where people can place order on any product of their choice and as well checkout their cart. I am at the point of checkout where a user selects his shipping address. I have a shipping app to handle the shipping address and I have an order app to handle the order and checkout. After implementing my codes I could not checkout a user who was supposed to be redirected to his paypal account(for now) and after creating shipping address for different users in the admin I also noticed that on the checkout page, it loads every shipping address instead of the customer's address (with the user logged in offcourse). I also noticed that when a user selects 'create new address radio button', it does not bring an address page for the user to create another shipping address. my codes are written below shipping models.py class AbstractAddress(models.Model): MR, MISS, MRS, MS, DR = ('Mr', 'Miss', 'Mrs', 'Ms', 'Dr') TITLE_CHOICES = ( (MR, _("Mr")), (MISS, _("Miss")), (MRS, _("Mrs")), (MS, _("Ms")), (DR, _("Dr")), ) title = models.CharField( pgettext_lazy(u"Treatment Pronouns for the customer", u"Title"), max_length=64, choices=TITLE_CHOICES, blank=True) first_name = models.CharField(_("First name"), max_length=255, blank=True) last_name = models.CharField(_("Last name"), max_length=255, … -

Custom JS for specific models in admin inline form
So I have followed https://docs.djangoproject.com/en/1.11/ref/contrib/admin/javascript/#inline-form-events to add custom JS to the change_form for my inline forms and it works but now I want to add different JS for a different model. This is not specific to the add and delete as described in above link. In my main app I have two models Invoices and Quotes that contain inline items InvoiceItems and QuoteItems. They both refer to the same change_form and therefore same formset_handlers.js file. The invoiceitem has some JS which takes qty, price etc and figures out the total plus some other js. I now want to add some new js for the quotes inline where the form ids and behaviour will be different. What I am looking for is a way to specify the JS file listed here {{ block.super }} <script type="text/javascript" src="{% static 'app/formset_handlers.js' %}"> </script> {% endblock %} Or a way to check for: $(document).on('formset:added', function(event, $row, formsetName) { if (formsetName == 'maininvoiceitem_set') { ... } else if (formsetName == 'mainquoteitem_set') { ... } without needing to specify added or delete. Unfortunately it does not seem as simple as leaving the :added or :delete off. -
Creating a .gitignore file for a Django website
I'm ready to push my existing Django project (which i've been running in a local environment) to a Bitbucket repository so I can run it on a public server. At the moment I feel like there's a lot of files created in local development that needs to be added to .gitignore. I found this .gitignore file on github however I still feel it's missing some things, for example it doesn't seem to remove files from each migrations folders. There's also a lot of stuff there that I don't know what they do - I understand not all of it is needed. Any advice is appreciated. -
How to delete an instance of a ManyToMany field in Django

I tried this but it's not working: act = Activity.objects.get(pk=pk) act.save() attendee, _ = Attendee.objects.get_or_create(student=request.user) **act.attendee.delete(attendee)** return...

Understanding Django user authentication system
I followed a couple of tutorials to create a custom authentication system and I'm trying to understand everything I'm doing because it doesn't work and I'm a bit lost. I have a class called CustomUserAuth that implements the "authenticate" method. In there, in the tutorial they simply do this to retrieve the user whose username is the same as we want: user = CustomUser.objects.get(username=username) since it didn't work even if I know I have that username in the database, I tried to print all the users: print(CustomUser.objects.all()) and I got that there were no users, and I don't really know why. My CustomUser inherits from AbstractBaseUser and in its code I have: objects = CustomUserManager() My CustomUserManager inherits from BaseUserManager. I tried to followed the source code in github but I don't know how and where Django access to the database. In my settings file I also added: AUTH_USER_MODEL = "custom_user.CustomUser" AUTHENTICATION_BACKENDS = ("custom_user.backends.CustomUserAuth",) My ultimate goal is to figure out why it doesn't work and it doesn't retrieve the users from the database, but I'm interested in knowing as well where does Django access the database. Thanks. -

Clear Google Cloud oAuth2 Token info when user's session ends
I'm working on a Python(3.6) & Django(1.10) project, in which I'm using some google cloud apis, I have used Google's OAuth2 for authentication, I have implemented it according to the google's documentation.It's saving the user's info in a file something called storage.json file first time and every time user is able to use this info when trying to authenticate with Google.

How to use docopt inside django view
I recently come across the python module docopt which is a command line parser which basically parsers the docstring you build to your program. I checked out the website and played around with it on http://try.docopt.org/ and found it useful that it works in the browser and thought it would be perfect for my django web app. After checking out the github repo at https://github.com/docopt/try.docopt.org i found the example was implemented in flask which i have never used and could not quite figure out how it worked. I have a script called votes.py that has a bunch of functions that i will be using but i just need the docopt to parse user command string from an ajax post request from a form element votes.py #A script with a bunch of example simple functions def get_vote_count(vote_candidate): vote_count = Votes.objects.filter(candidate = vote_candidate).count() return vote_count .... views.py #Will display candiate info def vote_info_list(request): template = 'app/vote.html' if(request.is_ajax() and request.method == 'POST'): command = request.POST.get("commmand","") #command string #e.g votes -c bob ''' I need to parse it here ''' If anyone can provide a simple docopt script solution that could work with this example to get me going will be greatly appreciated
