max_pages for other printouts

daniel · December 11, 2014, 7:25pm

Hi folks,

I am looking for a method to use “max_pages” and “num_page” in a non-standard printout type.

Especially I have build a macro where I want to use it:

{%- macro bottom(max_pages, page_num) -%}

{{ page }}
		 <p class="text-right">{{ _("Seite {0} von {1}").format(page_num, max_pages) }}</p>

{%- endmacro -%}

But when I include/import the macro, it gives me the error, that render.py and print.py cannot build the side.

Best,
Daniel

What is the error? Hard to guess without seeing the trace!

daniel · December 12, 2014, 7:00pm

rmehta: I copied and pasted the code

Traceback (innermost last):
  File "/home/erpnext/frappe-bench/apps/frappe/frappe/app.py", line 49, in application
    response = frappe.handler.handle()
  File "/home/erpnext/frappe-bench/apps/frappe/frappe/handler.py", line 66, in handle
    execute_cmd(cmd)
  File "/home/erpnext/frappe-bench/apps/frappe/frappe/handler.py", line 89, in execute_cmd
    ret = frappe.call(method, **frappe.form_dict)
  File "/home/erpnext/frappe-bench/apps/frappe/frappe/__init__.py", line 531, in call
    return fn(*args, **newargs)
  File "/home/erpnext/frappe-bench/apps/frappe/frappe/templates/pages/print.py", line 86, in get_html
    html = template.render(args, filters={"len": len})
  File "/home/erpnext/frappe-bench/env/local/lib/python2.7/site-packages/jinja2/environment.py", line 969, in render
    return self.environment.handle_exception(exc_info, True)

    reraise(exc_type, exc_value, tb)
  File "

This is how I try to call the macro:

{%- from "templates/print_formats/standard_macros_modified.html" import add_header,
     render_field, bottom -%}
{{ bottom(doc, page_num, max_pages) }}

Best,
Daniel

Anyone can reproduce the error??

rmehta · December 16, 2014, 7:03am

the trace is incomplete - can you share the trace from your bench console?

daniel · December 16, 2014, 10:15am

How to Do that
Daniel

daniel · December 16, 2014, 7:11pm

Well, basically everything is finished…but I need to get the page_num and max_pages into every macro and not only add_header…is this somehow possible @rmehta?

As you can see in the screenshot: everything is working except the macro for page_num and max_pages.

Best,
Daniel

rmehta · December 17, 2014, 4:51am

@daniel can’t help if you neither share the code or the trace!

daniel · December 17, 2014, 9:25am

@rmehta, thank you for your message.

Here is the code of the macro:
Pastebin Macro - daniel

Line 12: Calls num_page and max_pages
Line 139 & 140: Tried to display num_pages

Pastebin HTML Template - daniel

Here you can see how I want to call the standard-functions in the HTML Template.

This is the Error it gives me

Best regards,
Daniel

rmehta · December 18, 2014, 5:43am

@daniel - I am repeating myself - please don’t give the trace you see on your page (it is incomplete). Give the trace from your terminal.

daniel · December 18, 2014, 7:52am

Hi @rmehta, I really feel ashamed now to ask you this silly question, but I feel somehow stuck in a tunnel with no exit…how can I produce this traceback for you?

rmehta · December 19, 2014, 6:11am

What is your development environment?

Are you doing bench start on your terminal?

you can also don bench frappe --serve

daniel · December 19, 2014, 8:12am

Hi, some strange things happening…maybe this is why my last trace was not complete? For your information…have not modified the OS itself…only some DocTypes. Basically the only thing I’ve done is that I have set developer mode like described on frappe.io

Make sure to kill all your benches before starting bench again.

Are you running this from the frappe-bench folder?

daniel · December 25, 2014, 9:48am

Yes! I am Doing that within the folder

daniel · December 29, 2014, 12:01pm

hi @rmehta, I think we should terminate this issue…and delete the topic. I assume I should simply open a new one in order to get the right answer we are stuck like in a traffic jam now.

My original question was:
How can I use the variables “max_pages” and “num_pages” OUTSIDE of the “add_header” macro. This is the only thing that interests me at the moment…frappe is working, erpnext is working and I love what you have done.

rmehta · December 29, 2014, 12:21pm

Yeah I am lost too!

In principle, you should not add complex logic to Jinja Templates. How about identifying pages earlier while building the context and then passing the pages in the context itself.
