7.admin的自定制开发
10.实现与django admin filter_horizontal一样的复选框
实现效果：
首先要在king_admin中添加 filter_horizontal = ["tags"]
前段的页面：
1 <form class="form-horizontal" role="form" method="post" οnsubmit="return SeclectAllChosenDate()">
2 {% csrf_token %}
3 <span style="color: red">{{ form_obj.errors }}</span>
4 {% for field in form_obj %}
5 <div class="form-group">
6 <label class="col-sm-2 control-label" style="font-weight: normal">
7 {% if field.field.required %}
8 <b>{{ field.label }}:</b>
9 {% else %}
10 {{ field.label }}:
11 {% endif %}
12 </label>
13 <div class="col-sm-4">
14 {% if field.name in admin_class.filter_horizontal %}
15 <div class="col-md-5" >
16 {% get_m2m_obj_list admin_class field form_obj as m2m_obj_list %}
17 <select id="id_{{ field.name }}_from" multiple style="height: 200px!important; width: 100%;">
18 {% for obj in m2m_obj_list %}
19 <option value="{{ obj.id }}" οndblclick="MoveElementTo(this,'id_{{ field.name }}_to','id_{{ field.name }}_from')">{{ obj }}</option>
20 {% endfor %}
21 </select>
22 </div>
23 <div class="col-md-1" style="margin-top: 50px">
24 >> <<
25 </div>
26 <div class="col-md-5">
27 {% get_m2m_selected_obj_list form_obj field as m2m_selected_obj_list %}
28 <select tags="chosen_list" id="id_{{ field.name }}_to" name="{{ field.name }}" multiple style="height: 200px!important; width: 100%;">
29 {% for obj in m2m_selected_obj_list %}
30 <option value="{{ obj.id }}" οndblclick="MoveElementTo(this,'id_{{ field.name }}_from','id_{{ field.name }}_to')">{{ obj }}</option>
31 {% endfor %}
32 </select>
33 </div>
34
35 {% else %}
36 {{ field }}
37 {% endif %}
38 </div>
39 </div>
40 {% endfor %}
41
42 <div>
43 <div class="col-lg-5">
44 <button type="submit" class="btn btn-info pull-right" >保存</button>
45 </div>
46 </div>
47 </form>table_obj_change
实现前段的tags显示：
1 @register.simple_tag
2 def get_m2m_obj_list(admin_class,field,form_obj):
3 """返回待选标签数据"""
4 field_obj =getattr(admin_class.model,field.name)
5 all_obj_list = field_obj.rel.model.objects.all()
6 # print("-------",field_obj,all_obj_list)
7 if form_obj.instance.id:
8 selected_field_obj = getattr(form_obj.instance,field.name)
9 selected_obj_list = selected_field_obj.all()
10 # print("#########",selected_field_obj,selected_obj_list)
11 else:
12 return all_obj_list
13
14 standby_obj_list=[]
15 for obj in all_obj_list:
16 if obj not in selected_obj_list:
17 standby_obj_list.append(obj)
18
19 return standby_obj_list
20
21 @register.simple_tag
22 def get_m2m_selected_obj_list(form_obj,field):
23 """返回已选标签数据"""
24 if form_obj.instance.id:
25 field_obj =getattr(form_obj.instance,field.name)
26 # print(field_obj.all())
27 return field_obj.all()tags
注意：需要在views中的table_obj_change函数里面把admin_class传到前段
实现鼠标双击后标签的移动：
1 <script>
2 function MoveElementTo (ele,target_id,new_target_id) {
3 var opt_ele = "<option value='" + $(ele).val() + "' οndblclick=MoveElementTo(this,'"+ new_target_id +"','"+ target_id +"')>" + $(ele).text() + "</option>";
4 {#<option value="2" οndblclick="MoveElementTo(this,'id_tags_from','id_tags_to')">B类</option>#}
5 {#console.log(opt_ele);#}
6 $("#" +target_id).append(opt_ele);
7 $(ele).remove();
8
9 }
10
11 function SeclectAllChosenDate() {
12
13 $("select[tags='chosen_list'] option").each(function () {
14 $(this).prop("selected",true);
15
16 });
17 return true;
18
19 }
20
21 </script>table_obj_change
这是修改的标签的复选框设置，但是新增的复选框设置没有变化。。。
需要在table_obj_add函数把admin_class添加进去，然后设置
1 @register.simple_tag
2 def get_m2m_obj_list(admin_class,field,form_obj):
3 """返回待选标签数据"""
4 field_obj =getattr(admin_class.model,field.name)
5 all_obj_list = field_obj.rel.model.objects.all()
6 # print("-------",field_obj,all_obj_list)
7 if form_obj.instance.id:
8 selected_field_obj = getattr(form_obj.instance,field.name)
9 selected_obj_list = selected_field_obj.all()
10 # print("#########",selected_field_obj,selected_obj_list)
11 else:
12 return all_obj_list
13
14 standby_obj_list=[]
15 for obj in all_obj_list:
16 if obj not in selected_obj_list:
17 standby_obj_list.append(obj)
18
19 return standby_obj_list
20
21 @register.simple_tag
22 def get_m2m_selected_obj_list(form_obj,field):
23 """返回已选标签数据"""
24 if form_obj.instance.id:
25 field_obj =getattr(form_obj.instance,field.name)
26 # print(field_obj.all())
27 return field_obj.all()tags
最终效果：
后续：没有写全选设置，后续补充
11.开发删除页面
前段写上删除按钮： 在form标签内
1 <div class="form-group">
2 <div class="col-sm-2">
3
4 <a class="btn btn-danger" href="{% url "table_obj_delete" app_name table_name form_obj.instance.id %}">删除</a>
5
6 </div>
7 <div class="col-sm-4">
8 <button type="submit" class="btn btn-info pull-right" >保存</button>
9 </div>
10 </div>table_obj_change
url.py
re_path('(\w+)/(\w+)/(\d+)/delete/', views.table_obj_delete, name="table_obj_delete"),views.py
1 def table_obj_delete(request,app_name,table_name,obj_id):
2 """删除页面"""
3 admin_class = king_admin.enabled_admins[app_name][table_name]
4 obj = admin_class.model.objects.get(id=obj_id)
5
6 if request.method == "POST":
7 obj.delete()
8 return redirect("/king_admin/%s/%s/"%(app_name,table_name))
9
10 return render(request,"king_admin/table_obj_delete.html",{"obj":obj,
11 "admin_class":admin_class,
12 "app_name":app_name,
13 "table_name":table_name})Views
table_obj_delete.html
1 {% extends 'king_admin/table_index.html' %}
2 {% load tags %}
3 {% block container %}
4
5 <div>
6 {% display_obj_related obj %}
7 <form method="post">{% csrf_token %}
8 <input type="submit" class="btn btn-danger" value="Yes,I'm sure" />
9 <a class="btn btn-info" href="{% url "table_objs" app_name table_name %}" >No,Take me back</a>
10
11 </form>
12 </div>
13
14 {% endblock %}table_obj_delete
tags.py
1 @register.simple_tag
2 def recursive_related_objs_lookup(objs):
3 # model_name = objs[0]._meta.model_name
4 ul_ele = "<ul>"
5 print("----",objs)
6 for obj in objs:
7 li_ele = """<li> %s: %s</li>"""%(obj._meta.verbose_name,obj.__str__().strip("<>"))
8 ul_ele +=li_ele
9
10 #for local many to many
11 for m2m_field in obj._meta.local_many_to_many:
12 sub_ul_ele = "<ul>"
13 m2m_field_obj = getattr(obj,m2m_field.name)
14 for o in m2m_field_obj.select_related():
15 li_ele = """<li> %s: %s</li>"""%(m2m_field.verbose_name,o.__str__().strip("<>"))
16 sub_ul_ele +=li_ele
17 sub_ul_ele += "</ul>"
18 ul_ele +=sub_ul_ele
19
20 for related_obj in obj._meta.related_objects:
21 if "ManyToManyRel" in related_obj.__repr__():
22 if hasattr(obj, related_obj.get_accessor_name()):
23 accessor_obj = getattr(obj, related_obj.get_accessor_name())
24 # print("accessro_obj",accessor_obj)
25
26 if hasattr(accessor_obj, "all"): # 查询出来所有的数据
27 target_objs = accessor_obj.all()
28 sub_ul_ele = "<ul style='color:red'>"
29 for o in target_objs:
30 li_ele = """<li> %s: %s</li>""" % (o._meta.verbose_name, o.__str__().strip("<>"))
31 sub_ul_ele += li_ele
32 sub_ul_ele += "</ul>"
33 ul_ele += sub_ul_ele
34
35
36 elif hasattr(obj,related_obj.get_accessor_name()):
37 accessor_obj = getattr(obj,related_obj.get_accessor_name())
38 # print("accessro_obj",accessor_obj)
39
40 if hasattr(accessor_obj,"all"):# 查询出来所有的数据
41 target_objs = accessor_obj.all()
42 # print(target_objs)
43 else:
44 print("one to one i guess:",accessor_obj)
45 target_objs = accessor_obj
46
47 if target_objs:
48 nodes = recursive_related_objs_lookup(target_objs)
49 ul_ele +=nodes
50 ul_ele +="</ul>"
51 return ul_ele
52
53
54 @register.simple_tag
55 def display_obj_related(objs):
56 """把对象及所有相关联的数据取出来"""
57 objs = [objs,]
58 if objs:
59 model_class = objs[0]._meta.model
60 mode_name = objs[0]._meta.model_name
61 # print(model_class,mode_name)
62 return mark_safe(recursive_related_objs_lookup(objs))tags
效果：
12.action功能
实现action的功能，这样就可以自定制事件。例如：
前段页面： 设置checkbox全选和action的功能框
1 {% extends "king_admin/table_index.html" %}
2 {% load tags %}
3 {% block container %}

13.readonly fields只读
在添加页面有些字段我们不想更改，这样就需要这些字段是只读的
在king_admin中添加
readonly_fields = []
1 def create_model_form(request,admin_class): 2 3 def __new__(cls,*args,**kwargs): 4 for field_name,field_obj in cls.base_fields.items(): 5 field_obj.widget.attrs["class"] = "form-control" 6 if field_name in admin_class.readonly_fields: 7 field_obj.widget.attrs["disabled"] = "disabled" 8 9 10 return ModelForm.__new__(cls)
forms.py
但是有一个问题是，只读的字段一旦保存就出现错误，不能提交数据
所以只能用ajax把标签的diabled去掉
1 function SeclectAllChosenDate() {
2
3 $("select[tags='chosen_list'] option").each(function () {
4 $(this).prop("selected",true);
5
6 });
7 $("form").find("[disabled]").removeAttr("disabled");
8 return true;
9
10 }table_obj_change.html
这样就出现另外一个问题 在标签中修改数据后保存也是可以的，这就不行了。
14.kingadmin实现后端表单验证
1 def default_clean(self):
2 """给所有的form默认加一个clean验证"""
3 # print(self)
4 error_list=[]
5 for field in admin_class.readonly_fields:
6 field_val = getattr(self.instance,field)
7 field_val_form_frontend = self.cleaned_data.get(field)
8 # print(field_val,field_val_form_frontend)
9 if field_val != field_val_form_frontend:
10 error_list.append(ValidationError(
11 _('Field %(field)s is readonly, data should be %(val)s'),
12 code='invalid',
13 params={'field':field,"val":field_val},
14 ))
15
16
17 #自定制验证信息开始
18 self.ValidationError = ValidationError
19 response = admin_class.default_form_validation(self)
20 if response:
21 error_list.append(response)
22 #自定制验证信息结束
23
24 if error_list:
25 raise ValidationError(error_list)
26
27
28 setattr(_model_form_class,"clean",default_clean)forms
在customer中添加自定制验证信息：
1 def default_form_validation(self):
2 """定义一个自定制的验证"""
3 consult_content = self.cleaned_data.get("content","")
4 if len(consult_content) < 15:
5 return self.ValidationError(
6 ('Field %(field)s is 咨询的内容不能小于15个字符'),
7 code='invalid',
8 params={'field':"content"},)king_admin
效果:
单个字段的验证：
在customer中king_admin：
1 def clean_name(self):
2 """定义单个字段的验证"""
3 if not self.cleaned_data["name"]:
4 self.add_error("name","name is not null")
1 def __new__(cls,*args,**kwargs): 2 for field_name,field_obj in cls.base_fields.items(): 3 field_obj.widget.attrs["class"] = "form-control" 4 if field_name in admin_class.readonly_fields: 5 field_obj.widget.attrs["disabled"] = "disabled" 6 7 8 #定义单个字段的验证 9 if hasattr(admin_class,"clean_%s"%field_name): 10 field_clean_func = getattr(admin_class,"clean_%s"%field_name) 11 setattr(cls,"clean_%s"%field_name,field_clean_func) 12 13 return ModelForm.__new__(cls)
forms
效果：
针对m2m的tags字段的readonly验证：
1 def default_clean(self):
2 """给所有的form默认加一个clean验证"""
3 # print(self)
4 error_list=[]
5 for field in admin_class.readonly_fields:
6 field_val = getattr(self.instance,field) #val in db
7
8 if hasattr(field_val,"select_related"):#m2m
9 m2m_objs=getattr(field_val,"select_related")().select_related()
10 m2m_vals = [ i[0] for i in m2m_objs.values_list("id")]
11 set_m2m_vals = set(m2m_vals)
12 set_m2m_from_frontend =set([i.id for i in self.cleaned_data.get(field)])
13 if set_m2m_vals != set_m2m_from_frontend:
14 self.add_error(field,"readonly field")
15 continue
