问题 I'm trying to create a thread at Rails startup which will run throughout the lifetime of the app. The strange thing is, I already had this working with another thread I was running. I copied that (working) code and used it as boilerplate for the new code for the new thread. But the thread won't fire up. Code is in config/initializers (is this the correct place?). File is named starting with 'z_...' to insure it runs last. Rails 3.2.6 Here is the general structure of the code: class Blah def

问题 Ok, I am working on a Django application with several different models, namely Accounts, Contacts, etc, each with a different set of fields. I need to be able to allow each of my users to define their own fields in addition to the existing fields. I have seen several different ways to implement this, from having a large number of CustomFields and just mapping a custom name to each field used by each user. I have also seem recommendations for implementing complex mapping or XML/JSON style

问题 I just started learning Nhibernate and Fluent Nhibernate. I want to specify table name when I create my mapping class. Entity name in application is "CustomerOrders" but in the oracle database, table name is "CUSTOMER_ORDERS". I learnt from googling that I can use "WithTable" to specify database table name. I am not sure how to use it and where as Vs2008 didn't find the method. Thanks 回答1: WithTable was renamed to Table for the 1.0 release. It was mentioned in the release notes (first bullet

问题 I am creating an EMR cluster, and using jupyter notebook to run some spark tasks. My tasks die after approximately 1 hour of execution, and the error is: An error was encountered: Invalid status code '400' from https://xxx.xx.x.xxx:18888/sessions/0/statements/20 with error payload: "requirement failed: Session isn't active." My understanding is that it is related to the Livy config livy.server.session.timeout , but I don't know how I can set it in the bootstrap of the cluster (I need to do it

问题 I want to encrypt the connection strings in a web.config file in a shared hosting environment. I have read most of the articles on MSDN on the subject (http://msdn.microsoft.com/en-us/library/53tyfkaw.aspx) and concluded that I need to use RSAProtectedConfigurationProvider so that I can export the config file with key container to our shared hosting provider. However, when I do this I get an error "The RSA key container could not be opened." I assume this is because I need to grant access to

问题 I have a separate config file for my CakePHP application which is loaded in the bootstrap.php. My question is, how can I access the Configuration's variables in my Controller? I.e. How can I perform the Configure::read('variable') function in Controller? Thanks! 回答1: Please read the documentation. There it is explained quite well how to load custom config files: http://book.cakephp.org/2.0/en/development/configuration.html#loading-configuration-files By default, as documented in the class

问题 Seems that max_execution_time is 0 but memory_limit is -1 . For max_input_time is it 0 or -1 or both? 回答1: The absolute maximum value is the limit of the long type in C: long max_input_time; member in struct:_php_core_globals See: http://lxr.php.net/search?q=max_input_time&defs=&refs=&path=&hist=&project=PHP_5_4 The effective maximum value is 2147483647 , to maintain interoperability. It may be more on a specific platform or implementaion, but this is the most common, 32bit max. As you can

问题 I'm building a Multi-Tenant application and I'm struggling incorporating a Facebook Login into the web application. The tenants are using a sub-domain for example http://tenant-1.domain.com/ http://tenant-2.domain.com/ http://tenant-3.domain.com/ So, I have created an application and when it comes to add the Website, how can I make it to be available in all tenants?
