我对Pandas和Flask很新颖,试图利用它来输出包含调查反馈的汇总版本的CSV,我可以定期向用户发送电子邮件。Python烧瓶 - 将文件上传到Pandas
作为一个独立的函数,只要我给它一个指定的输入文件(例如'users/sample.csv')和outfile,但作为应用程序的一部分运行并使用上传的html文件时,失败 类型错误:csuppfb()至少需要2个参数(0给出)
基本上我想通过上传文件的功能,并有大熊猫做它的事,但它不会走到这一步。下面是代码:
import re,os
import beatbox
import pandas as pd
import numpy as np
import argparse
from jinja2 import Environment, FileSystemLoader
from weasyprint import HTML

UPLOAD_FOLDER = './uploads'
PIVOT_FOLDER = './pivot'
ALLOWED_EXTENSIONS = set(['csv'])
app = Flask(__name__)
app.config['UPLOAD_FOLDER'] = UPLOAD_FOLDER
app.config['PIVOT_FOLDER']= PIVOT_FOLDER
@app.route('/feedback',methods=['GET', 'POST'])
def feedback():
if request.method == 'POST':
file = request.files['file']
if file and allowed_file(file.filename):
filename = randomword(6)+'_'+secure_filename(file.filename)
file.save(os.path.join(app.config['PIVOT_FOLDER'], filename))
return redirect(url_for('csuppfb',df=filename))
return render_template('mappingtest.html')
@app.route('/csuppfb', methods=['POST','GET'])
def csuppfb(df,infile, index_list=["Case Owner","Case Number","Support Survey - Service rating"], value_list = ["Age (Hours)"]):
"""
Creating a pivot table from the raw dataframe and returning it as a dataframe
"""
table = pd.pivot_table(df, index=index_list, values = value_list,
aggfunc=[np.sum,np.mean], fill_value=0)
return table
def get_summary_stats(df, product):
"""

"""
results.append(df[df["Support Survey - Service rating"]==product]["Closed"].mean())
results.append(df[df["Support Survey - Service rating"]==product]["Age (Hours)"].mean())
return results
def dataform(df):
"""

"""
df = pd.read_csv(filename)
csuppreport = pivot_table(df,filename)
agent_df = []
for agent in csuppreport.index.get_level_values(0).unique():
agent_df.append([agent, csuppreport.xs(agent, level=0).to_html()])
env = Environment(loader=FileSystemLoader('.'))
template = env.get_template("csupp.html")
template_vars={"title": "CSUPP FB REPORT",
"Excellent": get_summary_stats(df,"Excellent"),
"Good": get_summary_stats(df,"Good"),
"csupp_pivot_table": csuppreport.to_html(),
"agent_detail": agent_df}
html_out = template.render(template_vars)
HTML(string=html_out).write_pdf(args.outfile.name,stylesheets=["style.css"])
return render_template('csupp.html')
什么是有我上传的 高清csuppfb(DF,INFILE ...
任何意见可以作为数据帧参数的文件的最好的办法非常感激。我感觉这件事情已经昭然若揭了我失踪。
