Add help_text for search field in admin.py

问题:

How can I add help_text in django for a search field I am using in admin.py as:

class ProfileAdmin(admin.ModelAdmin):

    list_display = ('First_Name','Last_Name','Registeration_No','University','Batch','Sex')

    search_fields = ('First_Name','Last_Name','Registeration_No','University','Batch')

回答1:

You can add this javascript in ModelAdmin

window.onload = function() {
    document.getElementById("searchbar").placeholder = "search with ";
};

ModelAdmin will be like

class SomeModelAdmin(admin.ModelAdmin):

    class Media:
        js = ('js/admin/custom_admin.js',)
        # css = { 'all': ('css/admin/custom_admin.css',)}

add the custom_admin.js in static/js/admin directory.

You could either override Admin template admin/search_form.html to add help text;
Or load a javascript file, which could find the dom node to insert the help text, in ProfileAdmin.Media, check the doc.

The easiest solution is with jquery:

$("#searchfield_id").attr('title', "Click here to search for someone")

Or you can add it directly to the HTML itself. The title shows up when you mouse over the search field.

Answer just for myself!

1. Add an attr named search_fields_hint to my ModelAdmin subclass.
2. Edit admin.templates.admin.search_form.html
3. Add a attr placeholder="{{ cl.search_fields_hint }} to the <input>.
4. Edit admin.views.main.py, ChangeList class
5. Add self.search_fields_hint=search_fields_hint to the __init__.
6. Edit admin.options.py, about line 1468, add parameter self.search_fields_hint to ChangList.
