為了解決Django model save 的問題,作者鄧文淵,文淵閣工作室 這樣論述:
Python應用新經典! 繼暢銷書《Python初學特訓班》之後的 架站主題實戰代表作! 最佳熱門組合Python X Django, 讓你初學架站就上手! Python是目前最受歡迎的程式語言,Django堪稱是當前最熱門的Python網站框架,兩者結合,讓開發複雜的資料庫網站變得更簡單。本書一次綜合架站必備技能,提供相關範例檔,讓Python發揮極大效用,用Django打造出超強互動網站。 想要架站,唯有真正實戰,才是最佳體驗! ■零基礎建置Django開發環境,避開所有初學障礙。 ■正規化網站開發流程,由Django專案建立與app開發為主軸,領略其中
奧義。 ■新一代開發模式,使用視圖與模版學習Django運作方式,了解框架應用原理。 ■結合資料庫進行網站開發,運用Django資料庫結構與模式,提供詳細建置流程、操作方式與管理介面的方法。 ■以Django實作資料庫互動的操作精華「查詢、新增、修改與刪除」,讓資料庫應用不再是開發網站者的痛處。 ■運用Cookie與Session記錄瀏覽者與相關資訊,讓不同使用者能在同一網站中儲存並取得不同資料,使用不同服務。 ■深入Django使用者管理,簡單而全面的使用者認證,輕鬆完成網站登入/登出工作,帶入會員機制。 ■規劃5個主題實戰範例:包含新聞公告、網路留言版、網路相簿、電
子商務購物車,以及結合網路地圖的美食網頁,架構出專業實用的網站。 ■將網站部署到免費的知名雲端平台「Heroku」,展示自行架設的網站與後續管理都免煩惱。
以資料探勘方法探究 FACEBOOK 政治人物粉絲專頁網民角色分析
為了解決Django model save 的問題,作者許庭嫣 這樣論述:
本研究嘗試開發出一套可快速分析粉絲專頁中粉絲立場的系統。本論文以三位政治人物粉絲專頁為例,透過Facebook API撈取粉絲留言,並建置支持與不支持的詞彙列表,試圖快速地篩選出在一粉絲專頁中支持與不支持的留言粉絲與其留言。建置詞彙列表的方法為,透過人工標記判斷一留言為支持或不支持,並從該留言中擷取可作為詞彙列表的詞彙,評估方法為觀察準確率與召回率之變化。本研究透過抽樣詞彙列表判斷的結過給予人工進行標記,以來判斷該系統之品質。實驗結果顯示,在支持方面,本研究所建立的詞彙庫能夠判斷出97.57%的朱立倫支持粉絲數,最少的是蔡英文粉絲團,僅能夠判斷出67.41%的支持粉絲數;在不支持粉絲數方面,
則是蔡英文的最多,能夠偵測出32.58%,僅能偵測出朱立倫粉絲中的2.43%為不支持粉絲。比起支持詞彙列表,不支持詞彙列表的建置過程較為困難,原因為表達不支持的方式與詞彙較多,較不能如同支持詞彙般明確且較為固定。另外,不支持的留言往往會運用反諷的方式,留言中雖有支持的詞彙出現,但其語句意思實為不支持,因此提高了不支持詞彙列表增建的困難度。最後,本研究依據研究結果進行討論和提出未來研究相關建議。
網頁架構轉換輔助系統:一種可將網頁轉換為支援行動瀏覽之系統研究與開發
為了解決Django model save 的問題,作者吳怡萱 這樣論述:
現今行動網路及無線網路的環境技術成熟,人們使用行動裝置上網的比例超越了桌上型電腦,網頁開發者也須因應趨勢,根據使用者裝置提供良好的瀏覽介面,然而開發行動網站或重新架構網頁是十分耗費時間的。本研究提出可讓開發者透過簡單的步驟,將傳統網站架構轉換為響應式網頁架構的方法。本研究所開發之系統,在運行時可分為三個階段,第一階段根據開發者提供的資訊,透過本研究系統自動解析原網站內容並進行初步轉換。第二階段開發者可根據需求於本研究系統介面自行拖曳內容於框架,使畫面更具彈性。第三階段根據前階段所拖曳結果進行畫面設置,開發者可儲存轉換結果,進行後續開發,大幅減輕重新架構網頁的負擔。最後本研究以兩個無支援響應式
網頁的架構為應用案例,實際操作本研究系統,成功地將原架構轉換為響應式網頁架構,以驗證本研究所設計之系統有效性。
