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
