Problems with template context

[CleitonDeLima]

I'm getting some errors when use django-table2 or django-crispy-forms, I'm not sure why yet.
I decided to create this discussion while I investigate the problem further, perhaps there is something related to the type of context informed to the component.

I got this error when trying to upgrade from version 0.33 to 0.51.

Error

ValueError: dictionary update sequence element #0 has length 1; 2 is required

Temporary solution

class Component(View):
	def render(
        self,
        context_data: Dict[str, Any],
        slots_data: Optional[Dict[SlotName, str]] = None,
        escape_slots_content: bool = True,
    ) -> str:
        # context = Context(context_data) -> context_data is a RequestContext
        context = Context(context_data.flatten()) # < ----
        template = self.get_template(context)

I can't say if this really is a solution, I need to understand how the context behaves.

@CleitonDeLima Can you give the full stack trace so we can see where this happens?

[EmilStenstrom]

The error seems to originate from django_tables2/columns/templatecolumn.py? Is that using django-components?

https://github.com/jieter/django-tables2/blob/master/django_tables2/columns/templatecolumn.py#L68

[CleitonDeLima]

My django-component (component with name 'table') uses django_tables inside, it seems to me that some context changes coming from django-components affect elsewhere. still investigating.

[EmilStenstrom]

Relevant ticket: https://code.djangoproject.com/ticket/24765

[CleitonDeLima]

Maybe the problem is when rendering the component, the first Context() parameter needs to be a dict, but it receives a RequestContext.

[EmilStenstrom]

Where is the RequestContext object created? Who sends it there? I'm trying to understand django-component's role in this.

[CleitonDeLima]

Every template.Node is passed a context in the render method, the first context is a RequestContext (considering this within django's request and response cycle), not a dict.

https://docs.djangoproject.com/en/5.0/howto/custom-template-tags/#writing-the-renderer

[EmilStenstrom]

If changing the line of code that you suggest doesn't break any of the existing tests I'm open to changing it. Feel free to open a PR! I'd suggest adding a test too so we don't accidentally break this in the future.

[EmilStenstrom]

@CleitonDeLima We think we fixed it in 0.63 that was just released. We were creating a Context class from the incoming context data. Problem is, when we got a Context we were wrapping a Context in a Context, resulting in the above error downstream. Thanks for reporting!

[CleitonDeLima]

Thanks @EmilStenstrom , this solves the problem. (sorry for the English, it's not my native language)

[EmilStenstrom]

Happy to hear that!

Don't worry about english, none of the three most active people in the project (including me) has english as their first language. Viva Europe!
