[Tutorial] web forms tricks

Hi
web forms sometimes complex to work with especially when it’s changing and development added to it as it became better and better every version …
here is some of the things i learned after research you can find them here to follow :

1- for the listing page in portal here is how to add the headers of the list and the list content template html and the query to get them :

inside the controller you add this function like task.py for exampe inside doctype task, i also created folder called template to add my template html inside it you can put it any where but is see it more organized this way :

def get_list_context(context):
context.get_list = get_encounter_list #  query return the data to be render in lest 
context.row_template = "yourcusutomapp/module/doctype/doctypename/templates/task_row_template.html"
context.result_heading_template = "yourcusutomapp/module/doctype/doctypename/templateresult_heading_template.html"


def get_encounter_list(doctype, txt, filters, limit_start, limit_page_length = 20, order_by='modified desc'):
#what every sql or orm query  you get data  as_dict = True

2- how to write your permission if the current user have what every … then he can see this else redirect

class DoctypeName(Document):

	def has_webform_permission(self):

     """ this function return true or false  :
       true he can see the docname in portal , false no """

i use this function in case of no

   frappe.local.flags.redirect_location = '/me'
    raise frappe.Redirect

3- if you want to create your own view for portal to show data for task for example
you create HTML field and only show it and hide all other fields …
put html field as Empty Div , and use client script on event after_load to append element to Dom
before save you update the frappe.web_form.values [ they are hidden but you you populate them and the frappe controller see them now ]
the same case if you want to show already entered data in webform … you check if it contains values then render them to HTML field …

For filter link field, here is a much easier way.

frm.set_query('city', function() {
    return {
        'filters': {
			'area': frm.doc.area,
        },
    };
});

this works on Desk , but not on web forms as far as i know have you test it ?

Sorry, I misunderstood I thought you meant on desk form. :sweat_smile:

Modifying/Tweaking ERPNext Web Form DOM via JavaScript

Inside frappe.ready(), add callback using frappe.web_form.events.on('after_load', your_callback_here). Example:

function reloadCurrentStateOptions() {
	const countrySubdivisions = {{ country_subdivisions|tojson|safe }};
	// console.log('countrySubdivisions', countrySubdivisions);
	const currentStateSelect = $('select[data-fieldname="current_state"]');
	// console.log(currentStateSelect);
	currentStateSelect.html('<option></option>');
	for (const countrySubdivision of countrySubdivisions) {
		// console.log({value: countrySubdivision.name, text: countrySubdivision.title});
		currentStateSelect.append($('<option>', {value: countrySubdivision.name, text: countrySubdivision.title}));
	}
	// currentStateSelect.append($('<option>', {value: 'halo', text: 'yes'}));
	// console.log("");
}

frappe.ready(function() {
	// bind events here
	frappe.web_form.events.on('after_load', reloadCurrentStateOptions);
});

Hello, how to prompt a message and choices or options after saving the form

Hi @ahmadRagheb,
Would you show the code for doing this?
I’m not a programmer so got confused by how to pass values from webform to the other html page. I want to use this as confirmation page of the filled-in form.

Thanks a lot
