问题描述
除了标准Django字段外,我还具有带有个人资料图片字段的自定义用户模型。我也有用于创建用户的自定义表单。现在,我想允许我的用户编辑他们的个人资料信息,因为这是我的第一个Django项目,而且我没有经验,所以我不知道如何以简洁的方式重复使用注册表格
private void menuNavigation() {
bottomNavigation = (MeowBottomNavigation) findViewById(R.id.bottom);
fragment_container = findViewById(R.id.fragment_container);
bottomNavigation.add(new MeowBottomNavigation.Model(ID_HOME,R.drawable.ic_home));
bottomNavigation.add(new MeowBottomNavigation.Model(ID_BLE,R.drawable.ic_bluetooth));
bottomNavigation.add(new MeowBottomNavigation.Model(ID_ST,R.drawable.ic_heart));
bottomNavigation.add(new MeowBottomNavigation.Model(ID_TML,R.drawable.ic_folder));
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,new FragmentHome()).commit();
bottomNavigation.setonClickMenuListener(new MeowBottomNavigation.ClickListener() {
@Override
public void onClickItem(MeowBottomNavigation.Model item) {
}
});
bottomNavigation.setonReselectListener(new MeowBottomNavigation.ReselectListener() {
@Override
public void onReselectItem(MeowBottomNavigation.Model item) {
}
});
bottomNavigation.setonShowListener(new MeowBottomNavigation.ShowListener() {
@Override
public void onShowItem(MeowBottomNavigation.Model item) {
Fragment select_fragment = null;
switch (item.getId()) {
case ID_HOME:
select_fragment = new FragmentHome();
break;
case ID_BLE:
select_fragment = new FragmentBLE();
break;
case ID_TML:
select_fragment = new FragmentTML();
break;
case ID_ST:
select_fragment = new FragmentST();
break;
}
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,select_fragment).commit();
}
});
}
所以我去写另一种表格来编辑个人资料。
<activity android:name=".activitys.Home"
android:windowSoftInputMode="adjustPan"/>
让我感到困扰的是,我很乐意删除代码重复,但是不幸的是,我根本找不到用于用户编辑的任何好的示例,而且我不知道Django的处理方法是什么。第二件事是,如果我在总结时没有覆盖编辑表单的class CustomUserCreationForm(UserCreationForm):
class Meta(UserCreationForm):
model = CustomUser
fields = UserCreationForm.Meta.fields + ('profile_picture',)
username = forms.CharField(label='Enter Username',min_length=4,max_length=150)
email = forms.EmailField(label='Enter email')
first_name = forms.CharField(label='First name')
last_name = forms.CharField(label='Last name')
password1 = forms.CharField(label='Enter password',widget=forms.PasswordInput)
password2 = forms.CharField(label='Confirm password',widget=forms.PasswordInput)
profile_picture = forms.ImageField(label='Upload profile picture',required=False)
...
def save(self,commit=True):
user = CustomUser.objects.create_user(
username=self.cleaned_data['username'],first_name=self.cleaned_data['first_name'],last_name=self.cleaned_data['last_name'],email=self.cleaned_data['email'],password=self.cleaned_data['password1'],profile_picture=self.cleaned_data['profile_picture']
)
return user
,它只会将更改应用于个人资料图片。例如。如果我尝试更改图片,则可以使用,但是如果我更改class CustomUserEditForm(forms.ModelForm):
class Meta:
model = CustomUser
fields = UserCreationForm.Meta.fields + ('profile_picture',max_length=150,required=False)
email = forms.EmailField(label='Enter email')
first_name = forms.CharField(label='First name',required=False)
last_name = forms.CharField(label='Last name',required=False)
password1 = forms.CharField(label='Enter password',widget=forms.PasswordInput,required=False)
password2 = forms.CharField(label='Confirm password',required=False)
profile_picture = forms.ImageField(label='Upload profile picture',widget=forms.FileInput,required=False)
def save(self,commit=True):
user = self.instance
if user.username != self.cleaned_data['username']:
user.username = self.cleaned_data['username']
if user.first_name != self.cleaned_data['first_name']:
user.first_name = self.cleaned_data['first_name']
...
user.save()
return user
,则不能使用。它只是不更新名称值。这让我感到自己做错了非常严重的事情,因此我寻求建议和最佳实践指导以及可能的解释,以便更好地了解Django。
谢谢!
