Django HTML Array Form Passing
I have the following HTML form I am submitting to Django using post: input id="array" type="text" class="arrayinput" name="array[]" placeholder="Thing 1"> input id="array" type="text" class="arrayinput" name="array[]" placeholder="Thing 2"> input id="array" type="text" class="arrayinput" name="array[]" placeholder="Thing 3"> And in the model of this form I have: array = ArrayField(CharField(max_length=255, blank=True, null=True)) However when I submit this array, it tells me that the form is missing the field array. I assume this is because the field is called "array[]" but obviously I cannot name a python variable this. On the other hand, I cannot find any way to make a HTML array that has the functionality I need. -
How to add custom benefit in django-oscar?
Django-oscar provides multibuy benefit type. class MultibuyDiscountBenefit(Benefit): _description = _("Cheapest product from %(range)s is free") Now, I can add Buy 1 get 1 free offer with this benefit. I have a little custom requirement here. I want to add 'Buy 1 get 50% off on second' offer. To do so, I need to add custom benefit. I checked docs for adding custom benefit.

Following docs, I created my custom benefit for that. class MultiBuyCustom(Benefit): class Meta: proxy = True @property def description(self): """ Describe what the benefit does. This is used in the dashboard when selecting benefits for offers. """ return "But 1 and get 50% off" Here I don't know how to register this custom benefit to using in dashboard.? I need this benefit in the dropdown at dashboard while creating the offer. Any help would be greatly appreciated. -

How to use git to implement a simple versioning system?
I wish to create an interface where the user can list, upload and modify existing files. The user should also be able see the past snapshots of their files and permanently revert to a past snapshot if they so desire. My use case is similar to this. I am thinking of something like GitHub.com, but with a very simple interface that anyone will be able to understand (e.g. web interface only, one branch only, ...) What are the options available to create this kind of simple versioning system? Or should I need to integrate git into my Django project? (pointers on how to do this would be appreciated. It's my first time doing this.) -

Images not rendering in Django in pages with forms
Forewarning, I am very new to Django and Python in general. So my images render perfectly with all my other urls. But lets say I have a blog and when I edit a blog post, the url would be as follows: http://127.0.0.1:8000/post/14/edit/ Or for adding a comment: http://127.0.0.1:8000/post/3/comment/ And the images would not render for those urls. The pattern seems kind of obvious but I still don't know what the issue is. Now, if I was just creating a new post, with the url: http://127.0.0.1:8000/post/new/ The images render fine. Is this a caching issue or what? I've tried clearing my cache and it will work for a little bit and then fail to render later. Any suggestions? Thanks in advance! -

What is the best approach to handle user registration through invitation?

When user clicks for request invitation with an email address, a link will be send with token and when user clicks on that link, the user will be redirected to signup page.

Website that builds a graphic representation of visitors' choices building a product
I'm trying to build a website that will create a visual representation of a product based on the users' choices. Take for example, wreathed. On the first screen, the user would be presented with three options. When the make their choice, the base would be displayed. On the second screen, they would choose a bow and its placement, which would also be displayed. On so on... I'm currently learning Python/Django, so hopefully this would utilize a complementary framework/language. I understand the logic, just am not sure where to head to look for tying in the graphical aspect. I'm a quick learner, and learn best by doing, examples, tutorials, etc. Any help pointing me in the right direction would be greatly appreciated. Thanks! -
