Android Room - Get the id of new inserted row with auto-generate

情到浓时终转凉″ 提交于 2019-11-27 18:26:17
This is how I am inserting data into database using Room Persistence Library: Entity: @Entity class User { @PrimaryKey(autoGenerate = true) public int id; //... } Data access object: @Dao public interface UserDao{ @Insert(onConflict = IGNORE) void insertUser(User user); //... } Is it possible to return the id of User once the insertion is completed in the above method itself without writing a separate select query? Based on the documentation here (below the code snippet) A method annotated with the @Insert annotation can return: long for single insert operation long[] or Long[] or List<Long>

Persisting values in JavaScript object across browser refresh [duplicate]

若如初见. 提交于 2019-11-26 20:03:41
问题 This question already has answers here : Persist variables between page loads (4 answers) Closed 4 years ago . I have created a JavaScript object. var myObj = {}; Now as user plays-around with the application, we assign some values to this object. myObj['Name'] = 'Mr. Gates'; myObj['Age'] = 58; ... ... ... myObj['Role'] = 'CEO'; But whenever the page refresh's, the object looses its values. Is there any way using HTML 5\or any other technique to persist these values across page refresh. 回答1:

How persistent is localStorage?

只谈情不闲聊 提交于 2019-11-26 02:08:02
问题 I\'m depending heavily on localStorage for a plugin I\'m writing. All the user settings are stored in it. Some settings require the user the write regex\'es and they would be sad if their regex rules are gone at some point. So now I am wondering just how persistent the localStorage is. From the specs: User agents should expire data from the local storage areas only for security reasons or when requested to do so by the user. The above looks like it works just like cookies on the clientside. I

Persist variables between page loads

问题 I am trying to capture the submit button press of my form and if the form is submitted, the page refreshes and I show a few hidden fields. I would like to capture whether the form has been submitted before or not and if it submitted on reload, I would like to unhide the hidden fields. I was trying to use a global variable to achieve this, however I was unable to make it work properly. Here is what I tried: var clicked = false; $(document).ready(function() { $(\"input[type=\'submit\'][value=\
