How to display just the tags in form instead of all the list elements in Django?
I have a form used to create and edit an object on Django, and I'm trying to implement tags with django-taggit and Crispy Forms. Currently it's working great to create the tags, and it creates a list of tags for the field. When I want to edit the object I get the field pre-populated with those tags, but they are not 'flattened', so the tags show as: [<Tag:Tag1> <Tag:Tag2> <Tag:Tag3>] rather than just Tag1 Tag2 Tag3 And if the object contains no tags there is [] in the form field. My view to edit the objects is: def edit_recipe(request, recipe_id): """Edit an existing recipe""" recipe = get_object_or_404(Recipe, pk=recipe_id) if request.method == "POST": form = RecipeForm(request.POST, request.FILES, instance=recipe) if form.is_valid(): form.save() messages.success(request, "Successfully updated recipe.") return redirect(reverse("recipes")) else: messages.error(request, "Failed to update. Please check the form.") else: form = RecipeForm(instance=recipe) template = "recipes/edit_recipe.html" context = {"form": form, "recipe": recipe} return render(request, template, context) My model includes the field tags as so: tags = TaggableManager(blank=True) And my form is: class RecipeForm(forms.ModelForm): class Meta: model = Recipe fields = ( ... "tags", ) widgets = {"tags": forms.TextInput(attrs={"data-role": "tagsinput"})} What do I need to do to populate the form to edit an already existing … -

Get env variable from heroku
I have django project on heroku. On my Procfile i use 'release: bach./releast-tasks.sh' that will generate new env variable. web: gunicorn billions.wsgi --log-file - release: bash ./release-tasks.sh Here my release-tasks.sh: #!/bin/sh electrum daemon -d electrum setconfig rpcport 7777 pass=$(electrum getconfig rpcpassword) echo $pass export RPCPASSWORD=$pass The deploy (git push heroku master) is working fine and perfectly. I do not get any error. But now on my code i try to get "RPCPASSWORD" env variable like that : logger.info(os.environ.get('RPCPASSWORD', 'None')) It's alaways returning None. So 2 problems : I am not sure the env variable is really set with release-tasks.sh If it's correctly set, why i can't grab it with my django code :/ ? Thank for your help ! -
Add CSS to form field in django template
I want to use bootstrap on django form. To do so I need to add .form-control class to each field. My workaround is: def __init__(self, *args, **kwargs): super(SomeForm, self).__init__(*args, **kwargs) for field in self.fields: self.fields[field].widget.attrs = { 'class': 'form-control' } {% for field in form %} <div class="form-group"> {{ field.label_tag }} {{ field }} </div> {% endfor %} But I believe it's wrong to put CSS in python code (if I would want to use another CSS framework, I would have to change form class). How can I move the class to template? I would not like to use crispy not to be bound to bootstrap. -
TinyMCE with DigitalOcean Space in Django
I am currently working on building blog site using django and DigitalOcean Space. I've connected everything so static and media files automatically get saved to DigitalOcean space. However, I've been trying to get images in content (TinyMCE HTMLField()) get saved to DigitalOcean Space but seems to be not working. If I drag and drop the image to TinyMCE richtext area, it gets img src from my local path. If I do Upload, Source address seems to be generated with right path, but it's not saving the images to Space.

I feel lost with Django in every possible way
I am new to stack overflow so feel free to criticise if this ain't the kind of post to put on here, but I really don't know where else to ask then here where population is so big. I don't know how to start django project of my own.Yes I watched tutorials, got myself cheat sheets for django and html and am currently doing guide which explains things step by step and am doing and trying to understand as much as possible. The problem is even with all this, I've got only as far as navigating and making new directory with command prompt, loading virtual environment, running server and opening shell. I get the idea behind all the code in the guide that was written and what each line does but if you asked me to make a basic website on my own I wouldn't be able to do anything besides setting up the environment. Is there like a pattern to follow when making shit from scratch and do beginners like me even do anything from scratch or what?

Custom Form Field Naming Within Loop
I'm trying to specify field names within a loop on a form, so that the fields do not overwrite themselves. Right now I'm using this in my form: class TicketForm(forms.ModelForm): class Meta: model = Ticket exclude = ['products'] class ProductForm(forms.Form): product_id = forms.IntegerField() count = forms.IntegerField() class TicketProductForm(forms.ModelForm): class Meta: model = Ticket exclude = [] for Product in Product.objects.all(): product_id = forms.IntegerField(initial=Product.product_id) count = forms.IntegerField(initial=0) The for loop within TicketProductForm currently only displays one set of fields, as product_id and count overwrite the fields over and over, only displaying for the last entry in the set of Product. Is there a way to customize field names so that I can name them, preferably with a way I can set a specifier to allow easier lookup later? -
