get

问题 I'd like to have access to one my model field verbose_name. I can get it by the field indice like this model._meta._fields()[2].verbose_name but I need to get it dynamically. Ideally it would be something like this model._meta._fields()['location_x'].verbose_name I've looked at a few things but I just can't find it. 回答1: For Django < 1.10: model._meta.get_field_by_name('location_x')[0].verbose_name 回答2: model._meta.get_field('location_x').verbose_name 回答3: For Django 1.11 and 2.0: MyModel.

问题 In my controller/action: if(!empty($_POST)) { if(Auth::attempt(Input::get('data'))) { return Redirect::intended(); } else { Session::flash('error_message',''); } } Is there a method in Laravel to check if the request is POST or GET ? 回答1: Of course there is a method to find out the type of the request, But instead you should define a route that handles POST requests, thus you don't need a conditional statement. routes.php Route::post('url', YourController@yourPostMethod); inside you

问题 If i type this command: $ curl https://api.github.com/users/KiCad/repos | grep full_name I expect that it will return all KiCad repositories, but it returns: "full_name": "KiCad/Air_Coils_SML_NEOSID.pretty", "full_name": "KiCad/Buzzers_Beepers.pretty", "full_name": "KiCad/Capacitors_Elko_ThroughHole.pretty", "full_name": "KiCad/Capacitors_SMD.pretty", "full_name": "KiCad/Capacitors_Tantalum_SMD.pretty", "full_name": "KiCad/Capacitors_ThroughHole.pretty", "full_name": "KiCad/Choke_Axial

问题 SOLVED : I omitted the name attribute on the input fields. I have a simple html/php -form. And I submit it. The $_POST is always empty. If I try a get then the GET is always empty. Same for $_REQUEST and php://input. I get nothing in return. There a lot of posts with this subject, yet I have not found the solution for my problem. I do not have a rewrite or redirect. The method_request is POST. There is no clash with id's in the form, php://input is empty as well, REQUEST is empty as well. I

When method=

问题 My experience in jQuery is limited and I've searched around for an answer but can't seem to find it. This function returns a false or true based on a get. Now my problem is that the function 'Availability' doesn't return a false nor true if I get my data. This is the code. function Availability(){ var email = jQuery('#emailRegister').val(); jQuery.get("test.php", {email: email}) .done(function(data) { if(data == 'true'){ jQuery(".warningEmailDuplicate").hide(); return true; }else if(data ==

问题 I have an obscure issue. I am in the process of porting some Perl to Java and one of the methods in the Perl code posts to a jsp app and downloads a zip file. The working part of the Perl code is as follows which appears to be using a get to retrieve the file. $mech->get ( $url ); $mech->submit_form( fields => { upload => variable1, selectValue => variable2, }, ); The jsp page is as follows: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <meta http-equiv=

问题 When I syncdb and runserver everything works correctly in Django, but when I try to visit the webpage that it is on http://127.0.0.1:8000/ it returns a 404 error. Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/ Using the URLconf defined in MyBlog.urls, Django tried these URL patterns, in this order: ^admin/ The current URL, , didn't match any of these. The strange part is that when I visit /admin on the page it works fine. I dont understand what is failing here.
