c# - EF7 One to One relationships -


i'm working on getting handle on new ef7 , running odd behaviour when dealing 1 one relationships.

i have following models

public class material {     [key]     [required]     [column(typename = "bigint")]     public long id { get; set; }      [required]     [maxlength(128)]     public string name { get; set; }      [required]     [maxlength(512)]     public string description { get; set; }      [required]     [column(typename = "money")]     public decimal costperunit { get; set; }      public virtual unit unitofmeasure { get; set; }      [required]     [column(typename = "bit")]     public bool isactive { get; set; } = false; }   public class unit {     [key]     [column(typename = "bigint")]     public long id { get; set; }      [required]     [maxlength(32)]     public string name { get; set; }      [required]     [maxlength(64)]     public string description { get; set; }      [required]     public string type { get; set; } }

and building tables follows:

 builder.entity<unit>().key(u => u.id); builder.entity<unit>().property(u => u.name).maxlength(64).required(); builder.entity<unit>().property(u => u.description).required(); builder.entity<unit>().property(u => u.type).required();  builder.entity<material>().key(m => m.id); builder.entity<material>().property(m => m.name).required(); builder.entity<material>().property(m => m.description).required(); builder.entity<material>().property(m => m.costperunit).required(); builder.entity<material>().property(m => m.isactive).required();

the problem i'm having when try , query material unit of measure, unit of measure set null, when check generated tables can see foreign key created.

i've attempted force relationship in onmodel creating i'm still unable retrieve unit object.

builder.entity<material>().reference(m => m.unitofmeasure).inversereference().foreignkey<unit>(u =>

how should adding reference or supported yet?

how trying reference? lazy loading @ point not work in ef7. you'll have eager loading (dbcontext.materials.include(m => m.unitofmeasure)) or explicit version of that.

i have method allows user access comment have made on site. have post method lets them update comment. my normal solution send entire comment model through, let them update it, update on database when post back. involve sending commentid through in hiddenfor , can manipulated. how can verify commentid sent in get method same i'm getting in post , not able alter comment wish? how can verify commentid sent in method same i'm getting in post? basically have validate following things in post - user logged-in user. authenticated users post comments. commentid in post , should valid commentid , should present in database. userid associated logged-in user should same userid associated comment . comment should contain userid column, can check @ time of update. to make sure update happens comment has been sent in get - hold commentid in session , in post action compare commentid value in session .
