I'm having trouble outputing the relational data, I'm trying to get the title from the productive sections non- Object property, I have tried many ways, but I can not find the desired result 

  extends category product \ supernatural {public function producttype () {return $ this-> ; BelongTo ('product type', 'producttype_id'); }} Category Product Type Extended \ Supernatural {Public Function Products () {Return $ this- & gt; Hamind ("product", 'id'); }} $ Product- & gt; Product-type- & gt; The title of the title   
 update  
  are expanded \ Eloquent {protected $ fillable = ['keywords',' description ',' title ',' Slug ']; Protected $ table = "producttypes"; Public Function Products () {Return $ this- & gt; Has many ("product", 'product_id', 'id'); }} Expanding Class Productization \ Eloquent {protected $ table = "productvariations"; $ Fillable protected = ['product_id', 'producttype_id', 'price', 'quantity', 'discount', 'image']; Public Function Products () {Return $ this- & gt; Affiliation ('product'); }} Public Function Show ($ ID) {$ product = product :: with ('product type') - & gt; Searchoff file ($ ID) - & gt; get receive (); See Return: Creating ('products.show') - & gt; Products with ($ product); }   
 Show the page  
  $ product-> Product-type- & gt; Title   
 
 
 You should ensure that the query object returns and not the archive. If you are using a query as long as you do not get the collection of objects, as long as you get your query - & gt; Firstorfail () If you are using 'Model :: Search,' then you get the object so that you can use the method, look at the red note at the end of that section.  
 You should try  
  public function show ($ id) {$ product = Product :: Find ($ id); See Return: Creating ('products.show', ['product' => $ product]); }   
 will then be accessible to your visual product methods  
  $ product-> producttype; $ Product- & gt; Productivity // You must add this method to the product category

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i

I am trying to create Java web framework (and learning), and on the basis of 'Code Generator In the process of making the material view of the database in the process of development, I stumbled into a difficulty, which I do not know how to solve it.
