跟我一起学extjs5(37--单个模块的设计[5取得模块列表数据])
另一个是取得本条记录的标志字段的函数。
/**
* 依据module的数据来生成模块的model
*/
Ext.define('app.view.module.factory.ModelFactory', {
statics : {
getModelByModule : function(module) {
var model = Ext.define('app.model.' + module.tf_moduleName, {
extend : 'Ext.data.Model',
module : module,
idProperty : module.tf_primaryKey,
nameFields : module.tf_nameFields,
titleTpl : module.tf_titleTpl,
titleTemplate : null,
fields : this.getFields(module),
proxy : {
type : 'rest',
batchActions : true,
extraParams : {
moduleName : module.tf_moduleName
},
api : {
// 在这里加rest/是由于在web.xml中
// <url-pattern>/rest/*</url-pattern>这一句。spring会依据rest
// 后面的參数去进行匹配
read : 'rest/module/fetchdata.do',
update : 'rest/module/update.do',
create : 'rest/module/create.do',
destroy : 'rest/module/remove.do'
},
actionMethods : {
create : 'POST',
read : 'GET',
update : 'PUT',
destroy : 'DELETE'
},
reader : {
type : 'json',
root : 'records',
totalProperty : 'totalCount'
},
writer : {
type : 'json',
writeRecordId : true,
writeAllFields : false
// 没有改动过的字段不增加到update和delete的json中去
},
listeners : {
exception : function(proxy, response, operation) {
// 将出错信息加到proxy中去，传递到store的sync中显示出错信息。显示后将此属性删除
proxy.errorInfo = Ext.decode(response.responseText, true);
// 假设出错信息解析出错，则增加一个缺省的
if (!proxy.errorInfo)
proxy.errorInfo = {
resultCode : -1,
errorMessage : '未知原因:' + response.responseText
}
}
}
},
getTitleTpl : function() {
if (!this.titleTemplate) {
if (this.titleTpl)
this.titleTemplate = new Ext.Template(this.titleTpl);
else
this.titleTemplate = new Ext.Template('{' + this.nameFields + '}');
}
return this.titleTemplate.apply(this.getData())
},
// 此条记录能否够改动
canEdit : function() {
if (this.module.tf_hasAuditing && this.get('tf_auditinged'))
return false;
if (this.module.tf_hasApprove && this.get('tf_shNowCount') > 0)
return false;
return true;
},
// 此条记录能否够进行操作
canOperate : function() {
if (this.module.tf_hasAuditing && this.get('tf_auditinged'))
return false;
return true;
},
// 此条记录能否够删除
canDelete : function() {
if (this.module.tf_hasAuditing && this.get('tf_auditinged'))
return {
canDelete : false,
message : '【' + this.getTitleTpl() + '】已进行过审核，不同意进行删除操作!'
};
if (this.module.tf_hasApprove && this.get('tf_shNowCount') > 0)
return {
canDelete : false,
message : '【' + this.getTitleTpl() + '】正在审批或已经审批完毕,不同意进行删除操作!'
};
return true;
},
// 取得主键值
getIdValue : function() {
return this.get(this.idProperty);
},
// 取得当前记录的名字字段
getNameValue : function() {
if (this.nameFields)
return this.get(this.nameFields);
else
return null;
}
});
return model;
},
// String("String"), Boolean("Boolean"), Integer("Integer"),
// Date("Date"), Double("Double"), Float("Float"); Percent
getFields : function(module) {
var fields = [];
for (var i in module.moduleFields) {
var fd = module.moduleFields[i];
var field = {
name : fd.tf_fieldName,
title : fd.tf_title,
type : this.getTypeByStr(fd.tf_fieldType)
};
if (field.type == 'string') {
field.useNull = true;
field.serialize = this.convertToNull;
}
if (fd.tf_fieldType == 'Date') {
field.dateWriteFormat = 'Y-m-d';
field.dateReadFormat = 'Y-m-d';
}
if (fd.tf_fieldType == 'Datetime')
field.dateReadFormat = 'Y-m-d H:i:s';
field.tf_haveAttachment = fd.tf_haveAttachment;
fields.push(field);
}
return fields;
},
getTypeByStr : function(str) {
console.log(str);
switch (str) {
case 'String' :
return 'string';
case 'Boolean' :
return 'boolean';
case 'Integer' :
return 'int';
case 'Date' :
return 'date';
case 'Datetime' :
return 'date';
case 'Double' :
case 'Float' :
case 'Percent' :
return 'float';
default :
return 'string';
}
},
// 假设是空字符串，返回null
convertToNull : function(v) {
return v ? v : null;
}
}
});
2、在app.store的文件夹下生成文件GridStore.js。这是grid的Store的类的定义。
Ext.define('app.store.GridStore', {
extend : 'Ext.data.Store',
modulePanel : null,
remoteSort : true,
autoLoad : true,
autoSync : true,
leadingBufferZone : 100,
buffered : false, // buffered=true能够无限下拉。可是删除和新增，reload都有问题，临时不用
config : {
extraParams : {},
navigates : []
// 导航属性选中的情况
},
constructor : function(param) {
var me = this;
this.pageSize = 20;
this.extraParams = {};
this.navigates = [];
// 有创建时加进来的导航约束
if (param.modulePanel.param) {
var dnv = param.modulePanel.param.defaultNavigateValues;
this.setDefaultNavigates(dnv);
}
// ///////////
this.callParent(arguments);
},
listeners : {
// 调用proxy进行ajax的时候。将參数加进 store.proxy中，在调用完毕后。删除掉全部的extraParams參数
// 这样model.proxy就能够多store，互相不干扰了
beforeprefetch : function(store) {
for (var i in store.extraParams)
store.proxy.extraParams[i] = store.extraParams[i];
},
// buffered = true ,运行的是 prefetch
prefetch : function(store, records, successful) {
for (var i in store.extraParams)
delete store.proxy.extraParams[i];
},
// buffered = false ,运行的是 load
beforeload : function(store) {
// console.log(store);
for (var i in store.extraParams)
store.proxy.extraParams[i] = store.extraParams[i];
},
load : function(store) {
for (var i in store.extraParams)
delete store.proxy.extraParams[i];
}
}
});
3、改动app.view.module.Module类。把store 和 model的生成方式都改一下。
initComponent : function() {
console.log(this.moduleName + ' 正在创建');
// 从MainModel中取得当前模块的定义数据。包含字段和各种设置的信息
var mainmodel = this.up('app-main').getViewModel();
this.module = mainmodel.getModuleDefine(this.moduleName);
var viewmodel = new Ext.create('app.view.module.ModuleModel', {
// 将该模块的定义信息传递给本模块的viewModel
module : this.module
});
this.setViewModel(viewmodel);
this.glyph = this.getViewModel().get('tf_glyph'); // 因为上面的glyph的bind无效，因此须要在这里增加glyph的设置
this.model = app.view.module.factory.ModelFactory.getModelByModule(this.module);
this.store = Ext.create('app.store.GridStore', {
module : this.module,
model : this.model,
modulePanel : this
});
this.items = [{
xtype : 'navigate', // 导航区域
region : 'west',4、后台服务器端在com.jfok.server.controller下增加ModuleController.java,这是spring mvc 的控制类。
package com.jfok.server.controller;

5、在service包中增加ModuleService.java，用来完毕查询，新增，删除。改动的功能。
