Wagtail ModelAdmin只读

Question

使用Wagtails Modeladmin：

有没有办法禁用编辑＆amp;删除选项只留下检查视图？

我能想到的一种可能的方法是扩展模板，删除编辑和放大。删除按钮，然后以某种方式禁用编辑和删除视图。

有没有更清洁的方法？

编辑：感谢Loic回答，我可以理解。

PermissionHelper source code对于确定要覆盖的正确方法也非常有帮助。

仅显示检查视图的完整答案

class ValidationPermissionHelper(PermissionHelper):
    def user_can_list(self, user):
        return True  
    def user_can_create(self, user):
        return False
    def user_can_edit_obj(self, user, obj):
        return False
    def user_can_delete_obj(self, user, obj):
        return False

class ValidationAdmin(ModelAdmin):
    model = Validation
    permission_helper_class = ValidationPermissionHelper
    inspect_view_enabled = True
    [...]

可悲的是，您需要add change，delete或ModelAdmin该模型的权限（在角色中设置）才能显示。

解决方法是为class MyPermissionHelper(wagtail.contrib.modeladmin.helpers.PermissionHelper): def user_can_list(self, user): return True # Or any logic related to the user. class MyModelAdmin(wagtail.contrib.modeladmin.options.ModelAdmin): model = MyModel permission_helper_class = MyPermissionHelper modeladmin_register(wagtail.contrib.modeladmin.options.MyModelAdmin) 提供at least one并始终允许列表（并且仍然允许在角色中设置添加/更改/删除）：

typedef struct Student{
    char* firstName;
    char* lastName;
    int priority;
    int readingLevel;
    bookIds* wishlist;
    struct Student* next;
}student;    

student* buildStudentList(char* studentsFile, student* head)
{
    int i;
    FILE* fp;
    student* tempPtr = NULL;
    if((fp = fopen(studentsFile, "r")) == NULL)
        {
            printf("Unable to open file\n");
            return 0;
        }

    student* current = NULL;
    tempPtr = (student*)malloc(sizeof(student));
    tempPtr->firstName = malloc(sizeof(char)* NAME);
    tempPtr->lastName = malloc(sizeof(char)* NAME);

    while(fscanf(fp, "%s %s %d %d",tempPtr->firstName, tempPtr->lastName, tempPtr->priority, tempPtr->readingLevel) != EOF)
        {
            tempPtr->next = NULL;
            if(head == NULL)
                {
                    head = tempPtr;
                    current = tempPtr;
                    tempPtr = (student*)malloc(sizeof(student));
                }
            else
                {
                    current->next = tempPtr;
                    current = tempPtr;
                    tempPtr = (student*)malloc(sizeof(student));
                }
        }
    free(tempPtr);
    fclose(fp);
    return head;
}
