在博客應用程序中,用戶編寫帖子並為其選擇一些標籤。當用戶單擊“發布”時,它會執行publishPost操作,該操作會執行以下操作,但顯然不正確,因為在保存帖子時,標籤卻不會。儘管在控制台中沒有拋出任何錯誤: 動作:{ publishPost:function(){ var post = this.store.createRecord('post',{ 標題:this.get('title'), 正文:this.get('body') }); post.set('tags',this.get('newTags')); //標籤模型對象的數組(在模型文件中發布hasMany標籤) post.save(); } } 我也嘗試過直接添加標籤:this.get('newTags')到'post'對象: 動作:{ publishPost:function(){ var post = this.store.createRecord('post',{ 標題:this.get('title'), 正文:this.get('body'), 標籤:this.get('newTags') }); post.save(); } } 通常在Ember中如何處理? ****更新**** @Jeff我實現了您的建議,但是由於某種原因,它啟動了PATCH並在後端執行了SELECT(不是INSERT)語句(Rails w / JSONAPI)。有任何想法嗎? 在2018-02-26 22:21:43 -0800在:: 1開始發布POST“ / posts” 由PostsController#create作為API_JSON處理 參數:{“ data” => {“ attributes” => {“ title” =>“ asdfg”,“ body” =>“ gfdsa”,“ created-at” => nil,“ updated-at” => nil },“ type” =>“帖子”}} (0.2ms)開始 SQL(0.3ms)插入到posts(post)(title),body,created_at,updated_at中)VALUES(asdfg,gfdsa,2018-02-27 06:21:43) '2018-02-27 06:21:43') (1.1ms)提交 渲染文字模板 呈現的文字模板(0.0ms) 已完成201創建於9ms(查看:0.6ms | ActiveRecord:1.6ms) 在2018-02-26 22:21:43 -0800開始為:: 1啟用PATCH“ / tags / 18” 在2018年2月26日22:21:43 -0800開始為:: 1啟動PATCH“ / tags / 53” 由TagsController#update作為API_JSON處理 由TagsController#update作為API_JSON處理 參數:{“數據” => {“ id” =>“ 18”,“屬性” => {“名稱” =>“ AI”},“類型” =>“標籤”},“ id” =>“ 18“} 參數:{“ data” => {“ id” =>“ 53”,“ attributes” => {“ name” =>“ bigfoot”},“ type” =>“ tags”},“ id” =>“ 53“} (1.7ms)開始 (0.3ms)開始 標籤加載(1.1毫秒)從“標籤”中選擇“標籤”。*“標籤”。“ id” = 18“按標籤”排序。“ ID” ASC限制1 標籤加載(0.3毫秒)從標籤所在的標籤中選擇標籤。* id = 53 ORDER BY標籤.id限制ASC 1 (1.3ms)提交 (0.3ms)提交 渲染文字模板 渲染文字模板 呈現的文字模板(0.0ms) 呈現的文字模板(0.0ms) 在12ms內完成200 OK(查看:1.6ms | ActiveRecord:4.1ms) 10ms內完成200 OK(查看:0.9ms | ActiveRecord:0.9ms)

以下是我使用RESTApi的方式。 它可能不是最好的,也不是唯一的解決方案,對於JSONApi來說甚至可能有所不同。 publishPost:function(){ var post = this.store.createRecord('post',{ 標題:this.get('title'), 正文:this.get('body') }); post.save()。then(post => { 讓標籤= this.get('標籤'); //在這裡遍歷標籤 讓newTag = { foo:“ bar”, 發表:post }; let tag = this.store.createRecord('tag',newTag); tag.save(); //循環結束 }); } | 你的答案 StackExchange.ifUsing(“ editor”,function(){ StackExchange.using(“ externalEditor”,function(){ StackExchange.using(“ snippets”,function(){ StackExchange.snippets.init(); }); }); },“代碼段”); StackExchange.ready(function(){ var channelOptions = { 標籤:“” .split(“”), id:“ 1” }; initTagRenderer(“”。split(“”),“” .split(“”),channelOptions); StackExchange.using(“ externalEditor”,function(){ //如果啟用了摘要,則必須在摘要後觸發編輯器 如果(StackExchange.settings.snippets.snippetsEnabled){ StackExchange.using(“ snippets”,function(){ createEditor(); }); } 其他{ createEditor(); } }); 函數createEditor(){ StackExchange.prepareEditor({ useStacksEditor:否, heartbeatType:“答案”, autoActivateHeartbeat:否, convertImagesToLinks:是, noModals:是的, showLowRepImageUploadWarning:是的, 聲望:ToPostImages:10, bindNavPrevention:正確, 後綴:“”, imageUploader:{ brandingHtml:“採用\ u003ca href = \“ https://imgur.com/ \” \ u003e \ u003csvg class = \“ svg-icon \” width = \“ 50 \” height = \“ 18 \” viewBox = \“ 0 0 50 18 \” fill = \“ none \” xmlns = \“ http://www.w3.org/2000/svg \” \ u003e \ u003cpath d = \“ M46.1709 9.17788C46.1709 8.26454 46.2665 7.94324 47.1084 7.58816C47.4091 7.46349 47.7169 7.36433 48.0099 7.26993C48.9099 6.97997 49.672 6.73443 49.672 5.93063C49.672 5.22043 48.9832 4.61182 48.1414 4.61182C47.4335 4.61182 46.7256 4.91628 46.0943 5.50789C45.74.3 4.313.6662 4.313.6662 43.1481 6.59048V11.9512C43.1481 13.2535 43.6264 13.8962 44.6595 13.8962C45.6924 13.8962 46.1709 13.2535 46.1709 11.9512V9.17788Z \“ / \ u003e \ u003cpath d = \” M32.492 10.1419C32.492 12.6954 34.1182 14.048437.0451 14.0484 41.5985 12.6954 41.5985 10.1419V6.59049C41.5985 5.28821 41.1394 4.66232 40.1061 4.66232C39.0732 4.66232 38.5948 5.28821 38.5948 6.59049V9.60062C38.5948 10.8521 38.2696 11.5455 37.0451 11.5455C35.8209 11.5455 35.4954 10.8 521 35.4954 9.60062V6.59049C35.4954 5.28821 35.0173 4.66232 34.0034 4.66232C32.9703 4.66232 32.492 5.28821 32.492 6.59049V10.1419Z \“ / \ u003e \ u003cpath fill-rule = \” evenodd \“ clip-rule = \” evenodd \“ d = \“ M25.6622 17.6335C27.8049 17.6335 29.3739 16.9402 30.2537 15.6379C30.8468 14.7755 30.9615 13.5579 30.9615 11.9512V6.59049C30.9615 5.28821 30.4833 4.66231 29.4502 4.66231C28.9913 4.66231 28.4555 4.94978 28.1109 5.50789C6.723 4.5608.787 .1369 4.56087 21.0134 6.57349 21.0134 9.27932C21.0134 11.9852 23.003 13.913 25.3754 13.913C26.5612 13.913 27.4607 13.4902 28.1109 12.6616C28.1109 12.7229 28.1161 12.7799 28.121 12.8346C28.1256 12.8854 28.1301 12.9342 28.1301 12.983C28.14.3349 14.732 15.2321 24.1352 14.9821 23.5661 14.7787C23.176 14.6393 22.8472 14.5218 22.5437 14.5218C21.7977 14.5218 21.2429 15.0123 21.2429 15.6887C21.2429 16.7375 22.9072 17.6335 25.6622 17.6335ZM24.1317 9.27932C24.1317 7.94324 24.9928 7.09766 26.1024 27.2119 7.09766 28.0918 7.94324 28.0918 9.27932C28.0918 10.6321 27.2311 11.5116 26.1024 11.5116C24.9737 11.5116 24.1317 10.6491 24.1317 9.27932Z \“ / \ u003e \ u003cpath d = \” M16.8045 11.9512C16.8045 13.2535 17.2637 13.89629.31965 19.8079 13.2535 19.8079 11.9512V8.12928C19.8079 5.82936 18.4879 4.62866 16.4027 4.62866C15.1594 4.62866 14.279 4.98375 13.3609 5.88013C12.653 5.05154 11.6581 4.62866 10.3573 4.62866C9.34336 4.62866 8.57809 4.89931 7.9466 5.5079C7.510506203 4.963 5.00066 5.28821 5.00066 6.59049V11.9512C5.00066 13.2535 5.47873 13.8962 6.51203 13.8962C7.54479 13.8962 8.0232 13.2535 8.0232 11.9512V8.90741C8.0232 7.58817 8.44431 6.91179 9.53458 6.91179C10.5104 6.91179 10.893 7.58817 10.893 8.9410811.93.8962 C13.4375 13.8962 13.9157 13.2535 13.9157 11.9512V8.90741C13.9157 7.58817 14.3365 6.91179 15.4269 6.91179C16.4027 6.91179 16.8045 7.58817 16.8045 8.94108V11.9512Z \“ / \ u003e \ u003cpath d = \“ M3.31675 6.59049C3.31675 5.28821 2.83866 4.66232 1.82471 4.66232C0.791758 4.66232 0.313354 5.28821 0.313354 6.59049V11.9512C0.313354 13.2535 0.791758 13.8962 1.82471 13.8962C2.85798 13.8962 3.31675 13.2535 3.31675 11.9512V u003e \ u003cpath d = \“ M1.87209 0.400291C0.843612 0.400291 0 1.1159 0 1.98861C0 2.87869 0.822846 3.57676 1.87209 3.57676C2.90056 3.57676 3.7234 2.87869 3.7234 1.98861C3.7234 1.1159 2.90056 0.400291 1.87209 0.400291Zfill = \“#1BB76E \” / \ u003e \ u003c / svg \ u003e \ u003c / a \ u003e“, contentPolicyHtml:“根據\ u003ca href = \“ https://stackoverflow.com/help/licensing \” \ u003ecc by-sa \ u003c / a \ u003e \ u003ca href = \“ https://stackoverflow.com獲得許可的用戶貢獻/ legal / content-policy \“ \ u003e(內容策略)\ u003c / a \ u003e”, allowUrls:是 }, onDemand:是的, dispatchSelector:“。discard-answer” ,立即ShowMarkdownHelp:true,enableTables:true,enableSnippets:true }); } }); 感謝您為Stack Overflow提供答案!
