不正确的条目写入文件

我正在编写一个烧瓶应用程序，以便某人管理我的数据集。它应该在textarea中显示一条推文，并且该人员在单选按钮上选择选项并提交它，并将其写入文件中。然而，问题在于textarea中的推文显示与写入文件的推文显示不同。如果在文本区域中显示推文A，则即使该人评价推文A，也会将下一条推文即推文B写入该文件A.发生了什么问题？我的HTML模板和瓶代码都低于：不正确的条目写入文件

瓶：

from flask import Flask, render_template, request 
import csv 
app = Flask(__name__) 
with open('sqldata.csv', 'r') as f: 
     reader = csv.reader(f) 
     data = [row for row in reader] 
x = [] 
@app.route('/', methods=['GET','POST']) 
def index(): 
     datapoint = data[len(x)+1][2] 
     db={'Entry':datapoint} 
     if request.method == 'POST': 
      print request.form['Button1'] 
      but1 = request.form['Button1'] 
      but2 = request.form['Button2'] 
      print sent 
      but3 = request.form['Button3'] 
      with open('path/%s.csv' % but2, 'a') as f: 
       writer = csv.writer(f) 
       writer.writerows([(datapoint, but1)]) 
      with open('path/data.csv', 'a') as f: 
       writer = csv.writer(f) 
       writer.writerow([but3]) 
      x.append(len(x)) 
     return render_template('index.html', db=db) 
if __name__ == '__main__': 
     app.run(host, port,debug=True)

HTML模板：

<html> 
    <head> Sentiment Analysis Dataset</head> 
    <style> 
    .scrollabletextbox { 
height:50px; 
width:200px; 
font-family: Verdana, Tahoma, Arial, Helvetica, sans-serif; 
font-size: 82%; 
overflow:scroll; 
    } 
    </style> 
    <form method='POST'> 
      <b> Unclassified Text </b> 
      <textarea class='scrollabletextbox' name='Text' readonly> 
      {{db.Entry}} 
      </textarea> 
      <br> 
      <b> But2 </b> <br> 
      Positive:<input type='radio' name='Button2' value='1'><br> 
      Negative:<input type='radio' name = 'Button2' value='2'><br> 
      Noise:<input type='radio' name = 'Button2' value = '3'><br> 
      1<input type='radio' name = 'Button1' value='1'> 
      <input type='radio' name = 'Button1' value='2'>

你的表格中没有所谓的'Button1'或'Button2'或'Button3'元素...... – bernie

我编辑它，对不起 – lordingtar

没问题。 'print but3'给你什么？ – bernie

您可以使用值textarea的更新您的数据文件。请参阅下面测试的代码：

from flask import Flask, render_template, request 
import csv, os 
import jinja2 

app = Flask(__name__) 

with open('sqldata.csv','r') as f: 
    reader = csv.reader(f) 
    data = [row for row in reader] 

x = [] 
@app.route('/', methods=['GET','POST']) 
def index(): 
    datapoint = data[len(x)][2] 
    db={'Entry':datapoint} 
    if request.method == 'POST': 
     but1 = request.form['Button1'] 
     but2 = request.form['Button2'] 
     but3 = request.form['Button3'] 
     with open('%s.csv' % but2,'a') as f: 
      writer = csv.writer(f) 
      writer.writerows([(request.form['Text'], but1)]) 
     with open('data.csv','a') as f: 
      writer = csv.writer(f) 
      writer.writerow([but3]) 
     x.append(len(x)) 
    return render_template('index.html',db=db) 

if __name__ == '__main__': 
    loader=jinja2.FileSystemLoader(os.path.join(os.path.dirname(__file__),'templates')) 
    app.run(debug=True)

模板代码：

<html> 
    <head> Sentiment Analysis Dataset</head> 
    <style> 
    .scrollabletextbox { 
height:50px; 
width:200px; 
font-family: Verdana, Tahoma, Arial, Helvetica, sans-serif; 
font-size: 82%; 
overflow:scroll; 
    } 
    </style> 
    <form method='POST'> 
      <b> Unclassified Text</b> 
      <textarea class='scrollabletextbox' name='Text'>{{db.Entry}}</textarea> 
      <br> 
      <b> But2 </b> <br> 
      Positive:<input type='radio' name='Button2' value='1'><br> 
      Negative:<input type='radio' name = 'Button2' value='2'><br> 
      Noise:<input type='radio' name = 'Button2' value = '3'><br> 
      1<input type='radio' name = 'Button1' value='1'> 
      <input type='radio' name = 'Button1' value='2'> 
      <input type='radio' name = 'Button1' value='3'> 
      <input type='radio' name = 'Button1' value='4'> 
      <input type='radio' name = 'Button1' value='5'> 
      <input type='radio' name = 'Button1' value='6'> 
      <input type='radio' name = 'Button1' value='7'> 
      <input type='radio' name = 'Button1' value='8'> 
      <input type='radio' name = 'Button1' value='9'> 
      <input type='radio' name = 'Button1' value='10'>10<br> 
      <b>But3</b><br> 
      <input type='text' name='Button3'><br> 
      <input type='submit' value='Submit' name='Submit'> 
    </form> 
</html>
