在我的模板中,我有一个if语句来检查文件的类型,但是file_type字段是一个外键对象。如何获取要在if语句中使用的file_type.type字段?
模板:
{% for file in Site.sitefiles_set.all %}
{% if file.file_type != 'Site Plan' %}
模型:
class SiteFileType(models.Model):
type = models.CharField(max_length=200)
class Meta:
verbose_name = "File Type"
verbose_name_plural = "File Type"
def __unicode__(self):
return self.type
class SiteFiles(models.Model):
showroom_config_data = models.ForeignKey(ShowroomConfigData,verbose_name="Showroom")
major_site_info = models.ForeignKey(MajorSiteInfoData,verbose_name="Major Site")
site_image = models.ImageField(blank=True,upload_to=site_files_path)
site_file = models.FileField(blank=True,upload_to=site_files_path)
file_name = models.CharField(max_length=200,verbose_name="File Name (Optional)",blank=True)
file_type = models.ForeignKey(SiteFileType)
class Meta:
verbose_name = "Site Files"
verbose_name_plural = "Site Files"
def __unicode__(self):
return '%s | %s ' % (self.showroom_config_data.location, self.major_site_info.location)

您只需将type
附加到您已经拥有的变量(SiteFileType
对象):
{% for file in Site.sitefiles_set.all %}
{% if file.file_type.type != 'Site Plan' %}
...
{% endif %}
{% endfor %}

再按一点点跟随。
{% if file.file_type.type != 'Site Plan' %}
