crud

问题 I have some PHP pages that receive POST requests and make CRUD operations in my MySQL database... I would like to know if there is a way to allow only my Android application to do those requests in my pages... As my application requires Google Login (which Google IDs are already registered in my database), I was thinking in check if client's Google ID exists on database via PHP script, but it could be faked, right? Is there any other way to allow only my Android App to make CRUD in my

问题 I have a collection 'name' with 2 documents of the structure : doc 1: { a: 1 b : [{name:"AAA",age:10}, {name:"BBB",age:12}, {name:"CCC",age:13}] } doc 2 : { a: 2 b : [{name:"DDD",age:14}, {name:"EEE",age:15}, {name:"FFF",age:16}] } Since I am new to MongoDB, I am trying to find the difference of using the $elemMatch operator and not using it. Basically I am trying to query and find the first doc ( doc 1) with name AAA and age 10. So using the $elemMatch, my query looks like this : db.name

问题 In my symfony 2 project I have a bundle at src/Cinergy/Bundle/PeopleServiceBundle Now I'd like to generate a CRUD controller based on a doctrine entity, but I'm constantly failing to enter the correct string for the entity parameter. I tried things like: php app/console generate:doctrine:crud --entity=Cinergy/Bundle/PeopleServiceBundle:Group or php app/console generate:doctrine:crud --entity=@PeopleServiceBundle:Group All of them return erros like: [Doctrine\ORM\ORMException] Unknown Entity

问题 I'm using Codeigniter with Ion Auth for user management. I'd like to create two different user roles - one for volunteers and one for organizations. I know that I can use Ion Auth's groups for things like access control, but what would be a good way to add fields to the different user types (for instance - the volunteer user will have a 'languages spoken' field while the organization will have a 'mission' field)? Should I extend the Ion Auth class for each new user type and handle CRUD

问题 Using bean validation, particular hibernate validator implementation is it possible to define certain groups to automatically be used on certain crud operations like create or update? or are there some build in hibernate groups that are internally checked for those operations? 回答1: You're probably looking for "Hibernate event-based validation" under "ORM Integration". You can set properties to specify which groups to validate at different times by setting properties on the SessionFactory like

问题 I want to specifically set a field when a user is created. I have class RegistrationsController < Devise::RegistrationsController def create super @user.tag_list = params[:tags] end end I have check boxes that pass the tags parameter and I have verified in the server logs that the tags parameter is being passed. However, when I call @user.tag_list in the console I just get a blank response [] . I feel that the problem lies in my manipulating of the create method of devise. I have not

问题 Is there a simple way to write a common function for each of the CRUD (create, retreive, update, delete) operations in PHP WITHOUT using any framework. For example I wish to have a single create function that takes the table name and field names as parameters and inserts data into a mySQL database . Another requirement is that the function should be able to support joins I.e. it should be able to insert data into multiple tables if required. I know that these tasks could be done by using a

问题 What are some strategies that people have had success with for maintaining a change history for data in a fairly complex database. One of the applications that I frequently use and develop for could really benefit from a more comprehensive way of tracking how records have changed over time. For instance, right now records can have a number of timestamp and modified user fields, but we currently don't have a scheme for logging multiple change, for instance if an operation is rolled back. In a

问题 My question is quite simple. What is the best way to bring CRUD into a use-case diagram? It should be DRY. I know, UML is sometimes discretionary, but what do you think about it? Some ideas: 1 use-case diagram Not really DRY, if there are a few CRUD objects. 2 use-case diagram Not really DRY, if there are a few CRUD objects. 3 use-case diagram I prefer this. Update 4 use-case diagram (@Uffe) Note maybe needless, when it is described in the documentation? 5 use-case diagram (@home @Uffe) 回答1:

问题 i'm making a CRUD from a tutorial. And i'm getting this error. You have specified an invalid database connection group. What would be the problem? database.php - database config $db['default']['hostname'] = 'localhost'; $db['default']['username'] = 'root'; $db['default']['password'] = ''; $db['default']['database'] = 'cicrud'; $db['default']['dbdriver'] = 'mysql'; $db['default']['dbprefix'] = ''; $db['default']['pconnect'] = TRUE; $db['default']['db_debug'] = TRUE; $db['default']['cache_on']
