choice

问题 I was wondering how i should use my model choices options, in my ModelForm. Example(model): class NPCGuild(models.Model): CATEGORIES=( ('COM', 'Combat'), ('CRA', 'Crafting'), ('WAR', 'Warfare'), ) faction = models.ForeignKey(Faction) category = models.CharField(max_length=3, choices=CATEGORIES) name = models.CharField(max_length=63) My Form: class NPCGuildForm(forms.ModelForm): name = forms.CharField() category = forms.CharField( some widget?) faction_set = Faction.objects.all() faction =

问题 I am going step by step with the How to use Data Transformers The problem is that what if I want to do this with a Choice type? Which I dynamically populate with jQuery? I tested the example they provide (without creating a custom type..) and it works 100% with the text field type, but as soon as I change it to choice and give it empty choices it doesn't work, does this have to do with me populating the choices with jQuery after the page is loaded?

问题 How to use Locale::getDefault() for country field or in choice field with country names? I have tried -> add('agentCity','country') but I don't know how to use Locale::getDefault() 回答1: You can easily create a dropdown list of languages using the language field type: http://symfony.com/doc/current/reference/forms/types/language.html. Then you can specify the default value using empty_data , assuming that Locale::getDefault() is in the languages list: $form->add('agentCity', 'language', array(

问题 I've been using batch for a while now and I just recently ran into a problem I never encountered before involving ERRORLEVELS.

问题 A little more than three years ago I wrote an Access db to use for our bank accounts and budgeting. I've used it and loved it ever since because it does several great things that nothing else out there does. I've decided for several reasons to write it into an independent program.
