3 月,跳不动了?>>> Be careful with exec and eval in Python written on Tuesday, February 1, 2011 One of the perceived features of a dynamic programming language like Python is the ability to execute code from a string. In fact many people are under the impression that this is the main difference between something like Python and C#. That might have been true when the people compared Python to things like C. It's certainly not a necessarily a feature of the language itself. For instance Mono implements the compiler as a service and you can compile C# code at runtime, just like Python compiles code at

Storing API keys and passwords in web2py

被刻印的时光 ゝ 提交于 2020-03-05 07:10:53
问题 I am creating a web2py application which will pull a bunch of data from different sources. What's the best way to store the API keys and passwords? Appconfig.ini seems to me as a bad option here. 回答1: You can use the Python keyring lib to more safely store and retrieve an API key into the underlying Operating System's Keyring service. As an optional optimization, you can then store the key in Web2py's cache.ram to avoid having to retrieve API key from the OS for every request. See https:/

允我心安 提交于 2020-01-25 10:38:07
问题 I am trying to deploy a web2py application on GAE. When run locally, a phone_details table is defined in db.py using this line db.define_table('phone_details',Field('image',type='upload'),Field('name',unique=True),Field('screensiz'),Field('primcam'),Field('processor'),Field('ram'),Field('rom'),Field('os'),Field('company'),Field('price','integer')) To make it run on GAE, I created an entity in cloud datastore naming it 'phone_details' but there only string,boolean,number etc. are allowed

Migrating passwords from web2py to Django

ε祈祈猫儿з 提交于 2020-01-17 04:11:29
问题 I have passwords stored in web2py using SHA 512 algorithm. I am now migrating the models to django and hence need a way to hash passwords in django using SHA 512 in the same way as web2py does so that I can authenticate the old users with the same passwords.Please suggest some way. 回答1: According to this post a Python snippet to recreate the convention used in web2py would be the following: from hashlib import md5 import hmac hmac_key = '<your secret key>' password = 'insecure' thehash = hmac

Calculated Fields in web2py sqlgrid

我怕爱的太早我们不能终老 提交于 2020-01-15 15:58:23
问题 Web2py has several methods for calculated fields, but the documentation states that lazy fields "are not visualized by default in tables" because they don't come with attributes like _. In fact, they don't seem to be able to be available in SQLFORM.grid even if the field is requested. I get the error AttributeError: 'FieldLazy' object has no attribute 'readable' When I include a lazy field in the field list. db.mytable.myfield = Field.Lazy(lambda row: "calc") Can I put a lazy field into a

Post-login redirection in web2py

馋奶兔 提交于 2020-01-14 13:10:25
问题 I'm having trouble controlling post-login redirection behavior in web2py. According to this, web2py handles post-login redirection differently, depending on whether the login was initiated by the system (e.g. when accessing a auth-protected function) or by a user (when clicking a 'log in' link). In the former case, the behavior is to redirect to the referring page after login, as would be expected. In the latter, however, the user is redirected to an index page after login, or to a page
