Options for cloud based MS Access backend

阅读更多关于 Options for cloud based MS Access backend

问题 Our company has used Access for its database needs. It wants to stick with the current database frontend, but migrate the tables to some cloud based solution. We do not want to host SharePoint or pay a monthly fee for Office 365. I have used MySql as a backend, but we had to install drivers. We will also be gathering data from Google Forms on a regular basis. Can anyone suggest possible options for this combination? Data from Google Forms, Access frontend, and cloud based backend. Thanks! 回答1

阅读更多关于 TYPO3 / How to make repository from existing table fe_users?

问题 I am creating a special BE module with Extbase and Fluid and I need a domain object which would be representing standard FE user. When I create new domain object called e.g. Feuser and save it, the extension builder creates special repository and also wants to create special table tx_myextkey_feuser in database. But this table already exists as fe_users . Is possible to tell typo3 that the repository for Feuser objects already exists (as fe_users table) and that typo3 should use the existing

Django Multiple Authentication Backend for one project, HOW?

阅读更多关于 Django Multiple Authentication Backend for one project, HOW?

Need serious help here. I have an application written in django/python and I have to extend it and include some other solution as an "app" in this application. For example my app to be integrated is named "my_new_app" Now there is a backend authentication written for the main application and i cannot use it. I have a mysql db to query from and the main app uses cassendra and redis mostly. So my question is, is there any way i can use a separate authentication backend for the new app "my_new_app" and run the both in the same domain? Question may not be that clear, i'll clarify if asked. You can

Backend administration in Ruby on Rails

阅读更多关于 Backend administration in Ruby on Rails

I'd like to build a real quick and dirty administrative backend for a Ruby on Rails application I have been attached to at the last minute. I've looked at activescaffold and streamlined and think they are both very attractive and they should be simple to get running, but I don't quite understand how to set up either one as a backend administration page. They seem designed to work like standard Ruby on Rails generators/scaffolds for creating visible front ends with model-view-controller-table name correspondence. How do you create a admin_players interface when players is already in use and you

matplotlib won't draw python3

阅读更多关于 matplotlib won't draw python3

问题 I installed matplotlib successfully inside a virtualenv. Now I'm trying to get it to draw. I know how to change the backend, but I'm having a whole lot of trouble figuring out what to change it to. Has anyone managed to get it totally working with python3? If yes, how? I have tried a bunch of things. I have cycled through all the backends to see what all of the complaints are, not I'm trying to get just one of them to work. Also possibly worth noting is that my goal is to integrate it into a

Rails: store translations in database

阅读更多关于 Rails: store translations in database

I was searching for a plugin/gem solution to extend the native rails i18n for storing my translations into my database. Maybe I used the wrong search terms, but all I found was the information, that changing the backend IS actually possible and this blog entry which descripes how to write my own backend. It's hard to imagine, that all those rails apps out there having their translations stored in yml-files or every developer wrote own backends! Do you know working solutions for this? Storing multiline texts in yml really gets me down! ;) Thanks and greets, Joe i18n has built-in support for

How to switch Backend with Keras (from TensorFlow to Theano)

阅读更多关于 How to switch Backend with Keras (from TensorFlow to Theano)

I tried to switch Backend with Keras (from TensorFlow to Theano) but did not manage. I followed the temps described here but it doesn't work. I created a keras.json in the keras' directory (as it did not exist) but it doesn't change anything when I import it from Python. Create a .keras (note the . in front) folder in you home directory and put the keras.json file there. For example, /home/DaniPaniz/.keras/keras.json (or ~/.keras/keras.json in short) if you are on a UNIX like system (MacOS X, Linux, *BSD). On Windows you want to create the folder %USERPROFILE%/.keras and put the JSON file
