c# - Code first, Data is not inserting into database using cascading dropdown list -


In my [HTPT post] method, excluding all the data cascading drop down items, I have joined the department, subject and Section models are: There may be several sections of a department, there may be several sections of a topic. After submitting Jquery Deposit, it shows, the form can not be submitted! So it comes back to the index! Here is my code from the section controller: 

  [http post] [Valid Antiforganic tokens] Make public anecscent (section section) {if (ModelState.IsValid) {db.Sections.Add (section) ; Db.SaveChanges (); Return Redirect Action ("Index"); } ViewBag.DepartmentId = New Selection List (DB Dept., "DepartmentDirectory", "Name", Section Department ID); ViewBag.SubjectId = New Selection List (DB Shabeks, "Subject ID", "Subject Name", Section, Shadam Idi); See Return (Section); }   
 My creation under the Sieakon View. HTML is:  
  @model.models.Section @ {ViewBag.Title = "Create section"; } Action Script {& lt; Script type = "text / javascript" & gt; $ (Function () {$ .getJSON ("/ section / department / list", function (data) {var item = "& lt; option & gt; show list of department & lt; / option & gt;" $ Each (data, function i, department) {item + = "and lieutenant; option value = '" + department. Value + "'" gt; + + department. Text + "& lt; / option & gt;";} ); $ ("Value"), function (function () {$ .getJSON ("/ section / topic / list /" + $ ("# section> option: selected"). (Data) {var item = "& lt; Option> Show topic list & lt; / option & gt;"; $ .each (data, f) (Value,) {item = = "& lt; option value $ (" # subject "). Html (item);})}}}}} ="; $ (function () {$ ('' submit ("Click", function () {var form = $ (this) .Parent ("form"); $ .ajax ({type: "POST" Url: form.attr ('verb') , Data: form.serialize ()} .success (function () {warning ("your form has been submitted");}) .error (function () {alert ("Your form is not submitted"); }); Return false;});}); & lt; / script & gt;} & lt; h2 & gt; create section & lt; / H2 & gt; @using (Html.BeginForm ()) {@ Html.AntiForgeryToken () @ HTML.ValidationSummary (true) & lt; Fieldet & gt; & Lt; Story & gt; Section & lt; / Narrative & gt; & Lt; Label = "section" & gt; Departments & lt; / Label & gt; & Lt; Id = "section" name = "section" & gt; & Lt; / Select & gt; & Lt; Label = "topic" & gt; Subject & lt; / Label & gt; & Lt; Select ID = "topic" name = "topic" & gt; & Lt; / Select & gt; & Lt; Label = "section" & gt; Section & lt; / Label & gt; & Lt; Input id = "section" name = "section" type = "text" /> & Lt; P & gt; & Lt; Input type = "submit" id = "submit" value = "create" /> & Lt; / P & gt; & Lt; / Fieldset & gt; } & Lt; Div & gt; @html.exe link ("back to list", "index") & lt; / Div & gt;    
 
 
 I think you should have  name / id  your section Regarding your properties in both of your dropdown list.  
  section  to  DepartmentId  and  subject  to  SubjectId . They need to match in their  posts , the binder will attach the correct value

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
