我正在处理 Django 中的表单,我有一个包含大陆列表的选择字段,我需要处理选定的选项,这是来自我的数据库的 Select 请求:
def Select_continent():
db = MySQLdb.connect("localhost", "root", "aqw", "PFE_Project")
cursor = db.cursor()
sql = "SELECT Continent FROM myform_servercomponents"
try:
cursor.execute(sql)
results = cursor.fetchall()
continents = []
i=0
for row in results:
continents[i]=row[0]
i+=1
except:
print "Error: unable to fetch data"
db.close()
return continents
这是我的表格
def continents():
data = Select_continent()
i=0
continents=[]
for key,value in data:
continents.append(('i',value))
i +=1
return continents
class FilterForm(forms.Form):
Continent = forms.ChoiceField(choices=continents())
所以问题是我如何在我的视图中使用选定的选项
def affiche_all(request, currency):
if request.method == 'POST':
form = FilterForm(request.POST)
if form.is_valid() :
Continent = form.cleaned_data['Continent']
# here i need to send the selected choice to another view
# like this :
# continent == 'Europe'
#url = reverse('affiche_all', args=(), kwargs={'continent': continent})
#return HttpResponseRedirect(url)
任何想法 ???
