How to call 'set password' in Django using a fetch request - issue with csrfmiddlewaretoken?
I'm trying to create a 'reset password' function in my Django / React app. I'm using django-contrib-auth for the back end and most of this is working OK. However I can't get the POST request right in order to actually update the password. Here's the workflow. The user clicks a "forgot password" link and is shown a form where they enter their email address. They receive an email containing a link to click. They click the link and visit a page where they enter their new password twice and click "Submit". This is where the problem lies. If I use the built-in form generated by django-contrib-auth, the password is reset correctly. But I want to use a form generated by React, and in that page I'm sending a fetch request to the same endpoint. Here's a fetch request generated by the form which works: curl 'http://localhost:8000/api/v1/reset/Mw/set-password/' -H 'Cookie: meteor_login_token=OG2fh2iVTkn5AOujhdaBXCsetV-CQ1lS6ZLdtrtzFYC; csrftoken=uSEF8NQB0lUpimwfQcOWLt118igo0bQq2gbpTaGq7zvgQMeF4oM2cu3ZwfgmuDOa; sessionid=39awyoab3wouvxmacbzbxez2hrfoa498' -H 'Origin: http://localhost:8000' -H 'Accept-Encoding: gzip, deflate, br' -H 'Accept-Language: en-GB,en-US;q=0.9,en;q=0.8' -H 'Upgrade-Insecure-Requests: 1' -H 'User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36' -H 'Content-Type: application/x-www-form-urlencoded' -H 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8' -H 'Cache-Control: max-age=0' -H 'Referer: http://localhost:8000/api/v1/reset/Mw/set-password/' -H 'Connection: keep-alive' --data 'csrfmiddlewaretoken=ASbYGmwXWOTKagND1hWHK0DQt5Qo9MPq8gIIrJmM32uBIGv3ftUNb1FOR2QmDeNa&new_password1=sometext&new_password2=sometext' --compressed Here's my fetch request that … -
Accessing django template's dictionaries given a variable?
My question is if there's a way to obtain a value of a dictionary given a key. For example, imagine that my_dictionary is {1:'a', 2:'b', 3:'c'}and I have an attribute which is key which equals 1. How can I obtain 'a'? I tried with {{my_dictionary.key}}and {{my_dictionary.{{key}} }}but none of them worked. My idea is to do the same as with python, which is my_dictionary[key] but in a Django Template. Thank you -

How can I make it only submit selected fields? -

enumeration and capping items within either inlineformset_factory or modelformset_factory in Django
I have something that looks like this: https://imgur.com/gallery/9pnbBmJ and aside from adding a bit of "CSS/HTML makeup" I'm stuck here at the very last step of the very last leg of the project before I need to start looking into production settings and the like. Now, according to https://docs.djangoproject.com/en/2.1/topics/forms/modelforms/#inline-formsets (quite at the bottom; "Using an inline formset in a view") it should be possible to mass produce class objects, and it is, it would appear. I believe I'm on the right track, but I'm no expert in neither Python nor Django, unfortunately. What I'm trying to do is to: 1) limit/cap the objects to 9 items per user each of which may be edited later if the user should wish to do so, and 2) enumerate those items, ie. "(1), (2) ... (9)" so that I may avoid receiving the embarrasing MultipleObjectsReturned at /user/vulpes/ - get() returned more than one Gallery -- it returned 2! error. I've commented out some things: Firstly there's the matter of the modelformset_factory VS inlineformset_factory. I don't really know which to chose as the former returns one image per user whilst respecting the cap, while the latter returns many an image not respecting the cap … -

Changing error messages in django-rest-auth
Whenever I make a POST request with an empty username value, I get the following error message: "username": [ "This field may not be blank." ], I'd like to change this error message to my own custom error message.

How can I show my own custom error message? The unique error message shows up fine, it's just the blank one doesn't show up. -

How to limit fields returned in django queryset per field
I have rows of products, that tend to share some information, such as the same images (an image may show multiple products), descriptions, manufacturer, etc. I would like to choose some fields to only show the information once. I can't use distinct for this (I don't think) as the information is not always identicle, such as with the description, but may be only subtly different enough that I don't want to repeat it. At the moment, I am using a for loop to display fields from each result, which ends up with something like this: This is the code I am using in my view: def collection_detail(request, name=None): template = loader.get_template('/webapps/mywebapp/furniture/main_page/templates/main_page/detail.html') products = product.objects.filter(id=name) cart_product_form = CartAddProductForm() context={'products': products, 'cart_product_form': cart_product_form} return HttpResponse(template.render(context)) What would be the appropriate way to do this in a view, ignoring subsequent rows for some fields? -
