pyreports

pyreports

Codacy Badge CircleCI

pyreports is a python library that allows you to create complex reports from various sources such as databases, text files, ldap, etc. and perform processing, filters, counters, etc. and then export or write them in various formats or in databases.

Test package

To test the package, follow these instructions:

$ git clone https://github.com/MatteoGuadrini/pyreports.git
$ cd pyreports
$ python -m unittest discover tests

Install package

To install package, follow these instructions:

$ pip install pyreports #from pypi

$ git clone https://github.com/MatteoGuadrini/pyreports.git #from official repo
$ cd pyreports
$ python setup.py install

Why choose this library?

pyreports wants to be a library that simplifies the collection of data from multiple sources such as databases, files and directory servers (through LDAP), the processing of them through built-in and customized functions, and the saving in various formats (or, by inserting the data in a database).

How does it work

pyreports uses the tablib library to organize the data into Dataset object.

Simple report

I take the data from a database table, filter the data I need and save it in a csv file

import pyreports

# Select source: this is a DatabaseManager object
mydb = pyreports.manager('mysql', host='mysql1.local', database='login_users', user='dba', password='dba0000')

# Get data
mydb.execute('SELECT * FROM site_login')
site_login = mydb.fetchall()

# Filter data
error_login = pyreports.Executor(site_login)
error_login.filter([400, 401, 403, 404, 500])

# Save report: this is a FileManager object
output = pyreports.manager('csv', '/home/report/error_login.csv')
output.write(error_login.get_data())

Combine source

I take the data from a database table, and a log file, and save the report in json format

import pyreports

# Select source: this is a DatabaseManager object
mydb = pyreports.manager('mysql', host='mysql1.local', database='login_users', user='dba', password='dba0000')
# Select another source: this is a FileManager object
mylog = pyreports.manager('file', '/var/log/httpd/error.log')

# Get data
mydb.execute('SELECT * FROM site_login')
site_login = mydb.fetchall()
error_log = mylog.read()

# Filter database
error_login = pyreports.Executor(site_login)
error_login.filter([400, 401, 403, 404, 500])
users_in_error = set(error_login.select_column('users'))

# Prepare log
myreport = dict()
log_user_error = pyreports.Executor(error_log)
log_user_error.filter(list(users_in_error))
for line in log_user_error:
    for user in users_in_error:
        myreport.setdefault(user, [])
        myreport[user].append(line)

# Save report: this is a FileManager object
output = pyreports.manager('json', '/home/report/error_login.json')
output.write(myreport)

Report object

import pyreports

# Select source: this is a DatabaseManager object
mydb = pyreports.manager('mysql', host='mysql1.local', database='login_users', user='dba', password='dba0000')
output = pyreports.manager('xlsx', '/home/report/error_login.xlsx', mode='w')

# Get data
mydb.execute('SELECT * FROM site_login')
site_login = mydb.fetchall()

# Create report data
report = pyreports.Report(site_login, title='Site login failed', filters=[400, 401, 403, 404, 500], output=output)
# Filter data
report.exec()
# Save data on file
report.export()

ReportBook collection object

import pyreports

# Select source: this is a DatabaseManager object
mydb = pyreports.manager('mysql', host='mysql1.local', database='login_users', user='dba', password='dba0000')

# Get data
mydb.execute('SELECT * FROM site_login')
site_login = mydb.fetchall()

# Create report data
report_failed = pyreports.Report(site_login, title='Site login failed', filters=[400, 401, 403, 404, 500])
report_success = pyreports.Report(site_login, title='Site login success', filters=[200, 201, 202, 'OK'])
# Filter data
report_failed.exec()
report_success.exec()
# Create my ReportBook object
my_report = pyreports.ReportBook([report_failed, report_success])
# Save data on Excel file, with two worksheet ('Site login failed' and 'Site login success')
my_report.export(output='/home/report/site_login.xlsx')

Tools for dataset

This library includes many tools for handling data received from databases and files. Here are some practical examples of data manipulation.

import pyreports

# Select source: this is a DatabaseManager object
mydb = pyreports.manager('mysql', host='mysql1.local', database='login_users', user='dba', password='dba0000')

# Get data
mydb.execute('SELECT * FROM site_login')
site_login = mydb.fetchall()

# Most common error
most_common_error_code = pyreports.most_common(site_login, 'code')  # args: Dataset, column name
print(most_common_error_code)   # 200

# Percentage of error 404
percentage_error_404 = pyreports.percentage(site_login, 404)    # args: Dataset, filter
print(percentage_error_404)   # 16.088264794 (percent)

# Count every error code
count_error_code = pyreports.counter(site_login, 'code')  # args: Dataset, column name
print(count_error_code)   # Counter({200: 4032, 201: 42, 202: 1, 400: 40, 401: 38, 403: 27, 404: 802, 500: 3})
