Quitting Smarty to do it manually

由 大城市里の小女人 提交于 2019-12-01 15:15:14
I am facing the problem that I'm not really sure how to develop without a framework or a template engine. I started coding that way and now I want to go to basics. I used to work with this MVC schema, using Codeigniter and Smarty as a template engine. What I want to do now is to use raw php without both tools mentioned. I don't know how to "copy" the concept of Smarty's "block" and "extends". I used to define a base.tpl file which had html head, only the body tag, and the base css and js files (the ones that are always used in every page of the site), like this: (snippet) <!DOCTYPE html> <head

Python - extending properties like you'd extend a function

由 不羁岁月 提交于 2019-12-01 14:30:50
问题 Question How can you extend a python property? A subclass can extend a super class's function by calling it in the overloaded version, and then operating on the result. Here's an example of what I mean when I say "extending a function": # Extending a function (a tongue-in-cheek example) class NormalMath(object): def __init__(self, number): self.number = number def add_pi(self): n = self.number return n + 3.1415 class NewMath(object): def add_pi(self): # NewMath doesn't know how NormalMath

问题 So I am trying extend the base Application class and add member variables to create global variables like in this first solution of the link below. Android global variable This works if the member variable is a simple data type like a String or a Boolean . But how would you do it for a more complex data type? In my case i would like the member variable to be of type HashMap<String, Boolean> . I am setting three member variables in onActivityResult() (a boolean, a String , and a HashMap<String

IDEA and Eclipse : How to automatic generate method when extends a class

由 允我心安 提交于 2019-12-01 06:54:58
My question is extremely easy when you implement a class. (because Eclipse and IDEA can generate for us). But, I don't know how to do the same when you extends a class. (Of course this work is not must, but I want to be sure what to do in my code, so this option will be helpful). thanks :) For Eclipse, go into the Source menu ( Alt+Shift+s ) -> Override/Implement Methods... and this should give you a list of all the methods that can be @overriden. In IntelliJ : CTRL o shows the list of methods to override/implement In IntelliJ: Alt Insert generates all kinds of code, including overriding

Android: How to use the onDraw method in a class extending Activity?

由 淺唱寂寞╮ 提交于 2019-12-01 05:07:10
As a beginner, I've been building a simple counter application using a simple layout xml and a class called 'Counter', which derives (extends) from the class Activity. Now, I want to load a bitmap (png file) to place next to the counter. I've been reading up on onDraw(), but it requires the class to extend 'View'. I've been trying to create an object of this class to use this instead, to no avail. I'm a bit stumped about this concept, how to do it easily. If anyone could explain, I'd appreciate it. Simple example using onDraw function-it requires class to extend view Context to get the current

How to Inherit or Extend typeDefs in GraphQL

由 风格不统一 提交于 2019-12-01 04:23:33
I have a type User . Users can also be a type TeamMember . The only difference between a User and TeamMember is an added field teamRole: String . So, I’d love to do something like the following to avoid having to redundantly define all the user's fields… type User { id: ID!, name: String, (many other field defs) } type TeamMember extends User { teamRole: String, } Anyone aware of a syntax for this? I thought extend would be the answer, but it seems more like javascript’s prototype extend is great if you have a base schema and want to build two or more usable schemas based on it. You can, for

How to extend a class with a member of its own type?

由 China☆狼群 提交于 2019-12-01 01:14:44
Suppose we need to implement different types of tree with a class called "BaseNode" from which other type of Nodes are derived and it suppose to have an instance variable called parent of its own type, generally it looks like: class BaseNode{ //...some fields BaseNode parent; //...other methods } Now if I am going to derive Node for AVL tree with more members: class AVLNode extends BaseNode{ //...other useful stuff } the original parent (& left & right )node members will still be type BaseNode which prevents me to implement the AVL tree. Any one who could tell me how we could solve this
