[rik_sanchez]

Hi , any one have any idea on how can I filter this assign to dialog boxes User Link Type field ? When I click on the user a dialogue Box Opens Up with a User field . I want to filter it according to a field in the doctype .

You want to give permission according to doc type ? via the dialog box ?

[rik_sanchez]

Not Necessary permission , But I want to filter the drop down link field according to the project field it should show only the people mentioned n the project . I have made some customization in project doctype where users are defined . I want it to show only those users

Is this what you are looking for ?
it will give users to read and write permission.

or you want to share/show the doc to only some specific people ?

@rs115199789 i a not looking for that . when you click on the user who is assigned . it pops a dialogue box with a link field . i want to use set_query or any other way to fetch some users from a different doctype .

[rik_sanchez]

was able to achieve this by this . You can choose to trigger the function for different point . it needs some furnishing but this is the basic code . Module and User is my custom doctype
frontend

user_filter=(frm)=>{
    if (frm.doc.project) {
        frm.page.sidebar.find('.avatar-frame').on('click', function() {
            setTimeout(function() {
                let dialog = frappe.ui.open_dialogs[0];
                if (dialog && dialog.fields_dict) {
                    let user_field = dialog.fields_dict.user;
                    if (user_field) {
                        // Dynamically set the get_query function for the user field
                        user_field.get_query = function() {
                            return {
                                query: "path",
                                filters: {
                                    project: frm.doc.project
                                }
                            };
                        };
                        // Refresh the field to apply the new query
                        user_field.refresh();
                    }
                }
            }, 500); // Adjust the delay if necessary
        });
    }
}

backend

@frappe.whitelist()
def get_project_users(doctype, txt, searchfield, start, page_len, filters):
    project = filters.get('project')
    
    users = frappe.db.sql("""
        SELECT 
            user AS name
        FROM
            `tabModule and User`
        WHERE
            parent = %s
    """, (project,), as_dict=True)
    
    # Frappe expects a list of tuples (value, description)
    results = []
    for user in users:
        results.append((user['name'], user['name']))  # Using name for both value and description
    
    return results

where to apply this code and this assignment dialogue is custom dialogue box or is this functionality “assign to” given by frappe.
