Direct URL link for reaching specific form from external system

Anvil Q&A
1

We have an application with multiple forms on it. We want to redirect a user from another application (might be an Anvil application or an external application) to a specific form of Anvil application but I am not finding a way to do that.

Is there a standard way of doing this? Please help.

Anvil apps are Single Page Apps, so you can’t use the url as you would on other apps, but you can get the query string (the part after the #) as a dictionary. See the docs here: Anvil Docs | Navigation

The routing module of Anvil Extras builds on that to create a nice navigation system.

Use get_url_hash().

The followng code creates 3 unique URL links to 3 separate subform panels of a startup form named Home_page. The 3 sub-forms are named:

about_panel
getting_started_panel
more_info_panel.

You can access the 3 pages directly at the URLs:

https://yourappname.anvil.app/#?page=about
https://yourappname.anvil.app/#?page=getstarted
https://yourappname.anvil.app/#?page=moreinfo

from .about_panel import about_panel
from .getting_started_panel import getting_started_panel
from .more_info_panel import more_info_panel

class Home_page(Home_pageTemplate):
  def __init__(self, **properties):
    self.init_components(**properties)
    urlhash=get_url_hash()
    if dict=type(urlhash):
      if urlhash['page']=='getstarted':
        self.content_panel.add_component(getting_started_panel())
      elif urlhash['page']=='about':
        self.content_panel.add_component(about_panel())
      elif urlhash['page']=='moreinfo':
        self.content_panel.add_component(more_info_panel())
      else:
        self.content_panel.add_component(home_panel())

To be clear, this works in conjunction with sidebar menu links that look something like this:

  def link_1_click(self, **event_args):
    self.content_panel.clear()
    self.content_panel.add_component(about_panel())

  def link_2_click(self, **event_args):
    newpage=getting_started_panel()
    self.content_panel.clear()
    self.content_panel.add_component(newpage)
    newpage.label_1.scroll_into_view()

  def link_3_click(self, **event_args):
    newpage=more_info_panel()
    self.content_panel.clear()
    self.content_panel.add_component(newpage)
    newpage.label_1.scroll_into_view()
