使用Tkinter Treeview進行數據庫處理時看不到圖像

Question

我正在開發一個數據庫項目，運行以下代碼不會顯示給定的圖像。 完整的代碼可以在這里找到。

def populateProducts (self, productName, plist):
    rows = self.db.getProductsFromNameNIL(productName)
    auximage = Image.open ("/home/sourabh/Documents/Github/DBMS-Lab-Project/TkinterReference/small.png")
    self.auxphoto = ImageTk.PhotoImage (auximage)
    plist.delete (*plist.get_children ())
    for row in rows:
        print (row)
        plist.insert ('', 'end', text = '#0s text', values = row, image = self.auxphoto)
def browse (self):
    browseWin = Tk ()
    browseWin.title ("Browse Products")
    browseWin.protocol("WM_DELETE_WINDOW", lambda: self.on_closing (browseWin))  # handle window closing
    Label(browseWin, text = "Enter product name").grid (row = 0, column = 0, sticky = W)

    prodText = StringVar()

    Entry(browseWin, textvariable=prodText).grid (row = 0, column = 1, sticky = W)
    Button (browseWin, text = 'Switch to Login', command = lambda: self.switchToLogin (browseWin)).grid (row = 20, sticky = W, pady = 4)
    ############ Product List #############
    plist = ttk.Treeview (browseWin)
    plist['columns'] = ('pid', 'pname', 'sellerid', 'price', 'tstock', 'pickupaddress', 'description', 'rating')
    plist.heading('#0', text = 'Pic directory', anchor = 'center')
    plist.column ('#0', anchor = 'w', width = 200)
    plist.heading ('pid', text = 'Product ID')
    plist.heading ('pname', text = 'Product Name')
    plist.heading ('sellerid', text = 'Seller ID')
    plist.heading ('price', text = 'Price')
    plist.heading ('tstock', text = 'Total Stock')
    plist.heading ('pickupaddress', text = 'Pickup Address')
    plist.heading ('description', text = 'Description')
    plist.heading ('rating', text = 'Rating')
    plist['show'] = 'headings'
    plist.grid(row = 1, column = 0, rowspan = 18, columnspan = 50)
    Button(browseWin, text= 'Search', command= lambda: self.populateProducts (prodText.get (), plist)).grid(row=0, column = 2, sticky=W)
    browseWin.mainloop()

如果要運行項目進行測試，請在該GUI目錄中運行init.sh，方法是在終端中鍵入“ bash init.sh”，然后運行“ main.py”。 為了進行測試，請輸入詳細信息：'Nikhil'作為用戶名，'hi'作為密碼，然后選擇角色作為'Customer'，然后選擇'Enter'，然后選擇'Browse Products'，然后輸入'asg'。

固定！ 問題在於生產線

plist['show'] = 'headings'

刪除后，圖像出現。
