Question

我有一个模型，其中布尔字段可见并隐藏在使用admin.py我认为可以在页面上添加默认过滤器/ admin / articles / article /所以它有过滤器by visible = True和hidden = True

class ArticleAdmin(admin.ModelAdmin):
    list filter = [...]
    ...
    def changelist_view(self, request, extra_context=None):
        if not request.GET: #No filter
            #Perform filter to queryset for visible and hidden = True
        return super(ArticleAdmin,self).changelist_view(request, extra_context=extra_context)

在import java.io.BufferedOutputStream; import java.io.FileNotFoundException; import java.io.FileOutputStream; import java.io.IOException; import javax.swing.JTable; import javax.swing.table.TableColumnModel; import javax.swing.table.TableModel; import org.apache.poi.hssf.usermodel.HSSFCell; import org.apache.poi.hssf.usermodel.HSSFCellStyle; import org.apache.poi.hssf.usermodel.HSSFFont; import org.apache.poi.hssf.usermodel.HSSFRow; import org.apache.poi.hssf.usermodel.HSSFSheet; import org.apache.poi.hssf.usermodel.HSSFWorkbook; /* * To change this license header, choose License Headers in Project Properties. * To change this template file, choose Tools | Templates * and open the template in the editor. */ /** * * @author oluwajayi */ public class ExcelWriter { public static void Writer (JTable jTable1, String Location) throws FileNotFoundException, IOException { HSSFWorkbook fWorkbook = new HSSFWorkbook(); HSSFSheet fSheet = fWorkbook.createSheet("new Sheet"); HSSFFont sheetTitleFont = fWorkbook.createFont(); HSSFCellStyle cellStyle = fWorkbook.createCellStyle(); sheetTitleFont.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD); //sheetTitleFont.setColor(); TableModel model = jTable1.getModel(); //Get Header TableColumnModel tcm = jTable1.getColumnModel(); HSSFRow hRow = fSheet.createRow((short) 0); for(int j = 0; j < tcm.getColumnCount(); j++) { HSSFCell cell = hRow.createCell((short) j); cell.setCellValue(tcm.getColumn(j).getHeaderValue().toString()); cell.setCellStyle(cellStyle); } //Get Other details for (int i = 0; i < model.getRowCount(); i++) { HSSFRow fRow = fSheet.createRow((short) i+1); for (int j = 0; j < model.getColumnCount(); j++) { HSSFCell cell = fRow.createCell((short) j); cell.setCellValue(model.getValueAt(i, j).toString()); cell.setCellStyle(cellStyle); } } FileOutputStream fileOutputStream; fileOutputStream = new FileOutputStream(Location); try (BufferedOutputStream bos = new BufferedOutputStream(fileOutputStream)) { fWorkbook.write(bos); } fileOutputStream.close(); } }文件中注册您的模型，并在admin.py属性中提及您的模型字段。
