【CRM客户关系管理】21.action功能开发，默认action，生成自己的action

### DjangoAdmin后台增加actions功能  Django admin默认的执行，选中后，可以通过执行批量删除，也可以自定义一个函数去执行批量操作 修改crm/admin.py文件，增加`CustomerInfoAdmin(admin.ModelAdmin)`类的`actions` ```python class CustomerInfoAdmin(admin.ModelAdmin): list_display = ['name', 'contact_type', 'contact', 'consultant', 'consult_content', 'status', 'created_time'] list_filter = ['source', 'consultant', 'status', 'created_time'] search_fields = ['contact', 'consultant__name', 'consult_content'] readonly_fields = ['contact', 'status'] filter_horizontal = ['consult_courses'] actions = ['change_status'] def change_status(self, request, queryset): queryset.update(status=3) # 批量设置可装状态为“结业” change_status.short_description = '客户状态修改为结业' # 设置后台可见描述 admin.site.register(CustomerInfo, CustomerInfoAdmin) ```   选中后执行，就会把所有的状态修改为结业。 ### djadmin actions功能 #### 父类BaseDjAdmin增加actions属性 修改djadmin/djadmin_base.py ```python # djadmin/djadmin_base.py class BaseDjAdmin(object): list_display = [] list_filter = [] search_fields = [] readonly_fields = [] filter_horizontal = [] list_per_page = 5 actions = [] ``` #### 自定义crm的djadmin 可以直接将admin.py的属性和方法复制过来 ```python class CustomerInfoAdmin(BaseDjAdmin): # 不使用object，直接继承BaseDjAdmin list_display = ['name', 'contact_type', 'contact', 'consultant', 'consult_content', 'status', 'created_time'] list_filter = ['source', 'consultant', 'status', 'created_time'] search_fields = ['contact', 'consultant__name', 'consult_content'] readonly_fields = ['contact', 'status'] filter_horizontal = ['consult_courses'] actions = ['change_status'] def change_status(self, request, queryset): queryset.update(status=3) # 批量设置可装状态为“结业” change_status.short_description = '客户状态修改为结业' # 设置后台可见描述 site.register(models.CustomerInfo, CustomerInfoAdmin) ``` ### djadmin页面显示actions #### 增加执行按钮表单 修改table_detail.html，在`<table>...`上方增加执行表单 ```html <form> <div class="row"> <div class="col-md-3"> <select class="form-control" name="action"> <option value="">-------</option> {% for action in admin_class.actions %} <option value="{{ action }}">{{ action }}</option> {% endfor %} </select> </div> <div class="col-md-2"> <input type="submit" value="执行" class="btn btn-primary"> </div> </div> </form> <table class="table table-striped"> ...... </table> ```  #### 表格内容增加勾选框 修改table_detail.html的`<tbody><tr>`增加一行`td`，设置为复选框 ```html <tbody> {% for obj in queryset %} <tr> <td><input row-select="true" type="checkbox" value="{{ obj.id }}"></td> {% build_table_body obj admin_class %} <td><a href="{% url 'djadmin:table_delete' app_name model_name obj.id %}">删除</a></td> </tr> {% endfor %} </tbody> ``` #### 表格头部增加勾选框 修改table_detail.html的`<thead><tr>`增加一行`th`，设置为复选框 ```html <thead> <tr> <th><input type="checkbox" onclick="SelectALLObjs(this)"></th> {% if admin_class.list_display %} {% for display_field in admin_class.list_display %} <th> <a href="?_order={% get_sorted_data display_field current_order_field forloop.counter0 %}{% render_filter_args admin_class %}"> {{ display_field }} {% get_sorted_arrow display_field current_order_field forloop.counter0 %} </a> </th> {% endfor %} {% else %} {% build_table_head_name admin_class %} {% endif %} <th>操作</th> <!-- {% build_table_head_name admin_class %} --> </tr> </thead> ``` 还需要增加js代码，可以权限/取消全选下方表格内容的勾选，在`{% endblock %}`标签前面增加 ```html <script> function SelectALLObjs(ele) { if ($(ele).prop('checked')){ $('input[row-select]').prop('checked',true) }else{ $('input[row-select]').prop('checked',false) } } </script> ```
