django smart_selects，第二级不会填充 [英] django smart_selects, second level won't populate

问题描述

我无法获得第二个级别（子类别/ E_cat）下拉以填充。第一级（类别）似乎工作正常。我想我已经尝试了chained_field和chained_model_field选择的每一个合理的组合，没有成功。

I can not get the second level (subcategory/E_cat) drop down to populate. First level (Category) seems to be working fine. I think I've tried just about every reasonable combination of chained_field and chained_model_field selections without success.

我希望Equip表填充类别的ID，ID子类别。

I want the Equip table populate with the ID for the category and the ID for the subcategory.

下面是模型当前的样子。我究竟做错了什么？

Below is what the model currently looks like. What am I doing wrong?

model.py

model.py

class Category(models.Model):
    cat_no = models.IntegerField(null=True, blank=True)
    cat_txt = models.CharField(max_length=45)    
    def __unicode__(self):
        return self.cat_txt

class E_cat(models.Model):
    cat_no = models.ForeignKey(Category)
    cat_txt = models.CharField(max_length=45)
    scat_no = models.IntegerField(null=True, blank=True)
    scat_txt = models.CharField(max_length=45)
    def __unicode__(self):
        return self.scat_txt


class Equip(models.Model):
    category = models.ForeignKey(Category)
    subcategory = ChainedForeignKey(
        E_cat,
        chained_field="category",
        chained_model_field="cat_no",
        show_all=False,
        auto_choose=True,
    )
    manufacturer = models.CharField(max_length=35, blank=True)
    mfg_no = models.CharField(max_length=35, blank=True)
    size = models.CharField(max_length=35, blank=True)
    color = models.CharField(max_length=35, blank=True)
    quanity = models.IntegerField(null=True, blank=True)
    short_description = models.CharField(max_length=80, blank=True)
    location_zip = models.IntegerField(null=True, blank=True)
    listings = models.ForeignKey(Listings)
    info = models.TextField(null=True, blank=True)

包含此标签在jQuery版本2之后。它在Django 1.10和1.11版本中使用python 3.5.2完美地工作。
希望这有助于您

include this tag right after jQuery version 2 . It works perfrectly well in Django 1.10 and 1.11 version using python 3.5.2. Hope this helps you
