CRM 增加信息不进行readonly,自定义user
1、CRM 增加信息不进行readonly，只要在kind_admin/view.py中的table_objs_add函数加上admin_class.is_add_form = True，在前端做判断
def table_objs_add(request,app_name,table_name): """增加信息页面""" admin_class = kind_admin.enabled_admins[app_name][table_name] model_form_class = creat_model_form(request, admin_class) admin_class.is_add_form = True #admin_class.only_readonly = True if request.method == 'POST': form_obj = model_form_class(request.POST) #新增 if form_obj.is_valid(): form_obj.save() return redirect(request.path.replace("/add/","/")) else: form_obj = model_form_class() return render(request,"kindadmin/table_objs_add.html",{"form_obj":form_obj, "admin_class":admin_class})
2、为了使页面只读的不能够删除数据，可以在kind_admin.py 中加上readonly_table = False判断
发现了一个问题，之前自定义了一个clean_name函数，判断name不能为空，但是当我去修改name的名字时候，后端一直没有保存name的值，返回给前端的一直是None(求大佬指点)代码如下：
#判断name不能为空kind_admin.py def clean_name(self): print("name clean validation:", self.cleaned_data["name"]) if not self.cleaned_data["name"]: self.add_error('name', "cannot be null")
#判断名字不能为空,加到form的claen_name中 #判断admin_class里否有clean_name函数 if hasattr(admin_class, 'clean_%s' % field_name): #获取clean_name函数 field_clean_func = getattr(admin_class,"clean_%s" %field_name) #把clean_name函数添加到form的clean_field中 setattr(cls, 'clean_%s'%field_name, field_clean_func)
3、自定义user不用django自带的user
django的文档有：https://docs.djangoproject.com/en/1.10/topics/auth/customizing/
crm/models.py文件中
class UserProfile(AbstractBaseUser): email = models.EmailField( verbose_name='email address', max_length=255, unique=True, null =True ) name = models.CharField(max_length=32) is_active = models.BooleanField(default=True) is_admin = models.BooleanField(default=False) objects = UserProfileManager()#创建用户 USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['name'] #那个字段是必须的 def get_full_name(self): # The user is identified by their email address return self.email def get_short_name(self): # The user is identified by their email address return self.email def __str__(self): # __unicode__ on Python 2 return self.email def has_perm(self, perm, obj=None): "Does the user have a specific permission?" # Simplest possible answer: Yes, always return True def has_module_perms(self, app_label): "Does the user have permissions to view the app `app_label`?" # Simplest possible answer: Yes, always return True @property def is_staff(self): "Is the user a member of staff?" # Simplest possible answer: All admins are staff return self.is_admin
在Perfectcrm/setting.py中加下如下以让dajngo不用自带的
AUTH_USER_MODEL = 'crm.UserProfile' #crm app名 UserProfile用户表名
创建用户的函数crm/models：
class UserProfileManager(BaseUserManager): def create_user(self, email, name, password=None): """ Creates and saves a User with the given email, date of birth and password. """ if not email: raise ValueError('Users must have an email address') user = self.model( email=self.normalize_email(email), name=name, ) user.set_password(password) user.is_active = True user.save(using=self._db) return user def create_superuser(self, email, name, password): """ Creates and saves a superuser with the given email, date of birth and password. """ user = self.create_user( email, password=password, name=name, ) user.is_admin = True user.is_active = True user.save(using=self._db) return user
在crm/admin.py加上UserProfile用邮箱作为用户名
:
from django.contrib import admin
from django.contrib.auth.models import Group
from django.contrib.auth.admin import UserAdmin as BaseUserAdmin
from django.contrib.auth.forms import ReadOnlyPasswordHashField
class UserCreationForm(forms.ModelForm): """A form for creating new users. Includes all the required fields, plus a repeated password.""" password1 = forms.CharField(label='Password', widget=forms.PasswordInput) password2 = forms.CharField(label='Password confirmation', widget=forms.PasswordInput) class Meta: model = models.UserProfile fields = ('email', 'name') def clean_password2(self): # Check that the two password entries match password1 = self.cleaned_data.get("password1") password2 = self.cleaned_data.get("password2") if password1 and password2 and password1 != password2: raise forms.ValidationError("Passwords don't match") return password2 def save(self, commit=True): # Save the provided password in hashed format user = super(UserCreationForm, self).save(commit=False) user.set_password(self.cleaned_data["password1"]) if commit: user.save() return user class UserChangeForm(forms.ModelForm): """A form for updating users. Includes all the fields on the user, but replaces the password field with admin's password hash display field. """ password = ReadOnlyPasswordHashField() class Meta: model = models.UserProfile fields = ('email', 'password', 'name', 'is_active', 'is_admin') def clean_password(self): # Regardless of what the user provides, return the initial value. # This is done here, rather than on the field, because the # field does not have access to the initial value return self.initial["password"] class UserProfileAdmin(BaseUserAdmin): # The forms to add and change user instances form = UserChangeForm add_form = UserCreationForm # The fields to be used in displaying the User model. # These override the definitions on the base UserAdmin # that reference specific fields on auth.User. list_display = ('email', 'name', 'is_admin') list_filter = ('is_admin',) fieldsets = ( (None, {'fields': ('email', 'password')}), ('Personal info', {'fields': ('name',)}), ('Permissions', {'fields': ('is_admin',)}), ) # add_fieldsets is not a standard ModelAdmin attribute. UserAdmin # overrides get_fieldsets to use this attribute when creating a user. add_fieldsets = ( (None, { 'classes': ('wide',), 'fields': ('email', 'name', 'password1', 'password2')} ), ) search_fields = ('email',) ordering = ('email',) filter_horizontal = () # Now register the new UserAdmin... admin.site.register(models.UserProfile, UserProfileAdmin) # ... and, since we're not using Django's built-in permissions, # unregister the Group model from admin. admin.site.unregister(Group)
3、把之前创建的数据库删除：
drop database crm;
在此创建crm库：
drop database crm;
把在crm/migrations文件下的文件删除只剩下__init.py文件
然后再：
python3 manage.py makemigrations
python3 manage.py migrate
