What is the difference between slugurl and pageurl in wagtil

Question

I have two major query related to slugurl and pageurl:

What is the exact difference between slugurl and pageurl?

Why slugurl returning None ?

Answer 1

After debugging the source code found this in side the slugurl simple tag.

    @register.simple_tag(takes_context=True)
    def slugurl(context, slug):
        """Returns the URL for the page that has the given slug."""
        page = Page.objects.filter(slug=slug).first()

        if page:
            # call pageurl() instead of page.relative_url() here so we get the ``accepts_kwarg`` logic
            return pageurl(context, page)

1: What is the exact difference between slugurl and pageurl?

Both slugurl and pageurl are the tags

slugurl take slug string as the input where as pageurl take page object at the input.

NOTE: slugurl internally call the pageurl, if the page found with the mention string slug.

2: Why slugurl returning None.?

If you passing any string( let say 'hello') in the slugurl, then the string must be the slug of any Page

 page = Page.objects.filter(slug=slug).first()

If the mention string is not assign as the slug of any page, the method will return None

In case you are facing the None issue with slugurl then follow these two simple steps:

1:Firstly check that any of your page have the mention slug or not.

2:In case of not, please create a page and assign the same slug string in the slug of the newly create page.
