Todo List Html Template NEW! Free Download
Analisa Wisdom
This example demonstrates how to create a todo list app using the Model, Model List, and View components. The example also includes a custom sync layer that stores the todo items in localStorage (in browsers that support it).
Ironically, this example complexifies a very simple application in order to demonstrate concepts you might actually use to simplify a complex application. In reality, this little todo app is so conceptually simple that it probably doesn't need to be broken into discrete components, but its inherent conceptual simplicity makes it convenient for explaining how models, model lists, and views work.
The TodoView class extends Y.View and customizes it to represent the content of a single todo item in the list. It also handles DOM events on the item to allow it to be edited and removed from the list.
Line 24 declares what is perhaps the most interesting field, ToDoItem.todo_list. This field is declared as a foreign key. It links the ToDoItem back to its ToDoList, so that each ToDoItem must have exactly one ToDoList to which it belongs. In database lingo, this is a one-to-many relationship. The on_delete keyword in the same line ensures that if a to-do list is deleted, then all the associated to-do items will be deleted too.
Line 17 introduces the template syntax % url "index" % as the target of an onclick event handler. The Django template engine will find the urlpatterns entry named "index" in the URLConf file todo_app/urls.py and replace this template with the correct path. The effect of this is that a click on the Django To-do Lists heading will cause the browser to redirect itself to the URL named "index", which will be your home page.
So base.html is a complete web page, but not very exciting as it stands. To make it more interesting, you need some markup to go between the % block content % and % endblock % tags.The inheriting templates will each supply their own markup to fill this block.
Lines 10 to 20 define a loop bracketed by the % for todolist in object_list % and % endfor % tags. This construct renders the enclosed HTML once for each object in the list. As a nice bonus, the % empty % tag in line 18 lets you define what should be rendered instead, if the list is empty.
Line 6 tells Django that if the rest of the URL is empty, your ListListView class should be called to handle the request. Notice that the name="index" parameter matches the target of the % url "index" % macro that you saw in line 18 of the base.html template.
The DeleteView subclass will still be in control when this template is rendered. By clicking the Yes, delete. button, you submit the form, and the class goes ahead and deletes the list from the database. If you click Cancel, it does nothing. In either case, Django then redirects you to the home page.
There are many types of html tags that allow us to specify what type of content we are adding to a page: headings, paragraphs, bulleted lists, etc. Sometags can hold other tags inside of them which allows us to work towards creating complex webpages.
When we click the submit button that we defined in our create-todo.html file, we want to show the user that they succesfully created a new todo item. The easiest way to do this is by setting up a new HTML template that we will render instead of create-todo.html when the user submits the form. For now we will hardcode the success view, but later we will actually show the new todo.
The title syntax is similar to what you have already worked with while using f-strings. In our case we are telling our success.html template to expect two str variables named title and description.
One hallmark of any great todo list is the ability to mark items as complete or incomplete. In this extension, you will modify individual todo list items to contain a button which will check them off, and use some additional styling to visually distinguish complete items from incomplete ones.
In this bonus task you will add the ability to edit your tasks from the view list page. We will do this using a feature of flask that allows us to use variables in our routes. We can make use of this feature in order to show an edit page for an individual todo.
Lets define two more files in our templates directory for displaying an edit form page and successful edit page. Create a new file in templates named edit-todo.html. Copy and paste the contents of your create-todo.html file into the new edit file.
Create a new file in templates named edit-success.html. Copy and paste the contents of your success.html file into the new success file. Update the contents of this file to say something about a successful edit instead of a successful creation. You can also add the following html tag somewhere in your body for an easy way of returning to the view list page:
This route is slightly more complex than ones we have defined previously. The syntax defines an unknown in the URL with a variable name of todo_number. When this route is accessed, it will pass the given todo_number to the edit_todo function. Then the todo_number can be converted to an int and used to select the correct todo our of our todos list. For instance, if we navigate to the URL /edit-todo2, we could expect to be shown all the data about the third todo that was created. (Since we started at 0)
This was an opportunity to play with HTMX, which is new to me and I hadn't really built anything with it before this week. The same goes for templ as well. I thought the two worked well together and I find using templ a much better experience than I've had in the past using the html/template library.
In the video generate a scaffold, at around 4:00 he has created a todo list, is able to edit it, and finally deletes (destroys) the list.I am able to do all of this except to destroy the list.When I click destroy within my rails app, it directs me to just view the todo list that I created, instead of deleting it.I do not know why this is happening, as I coded my todo list as was shown in the videos. If someone has had this issue with rails or has any insight into this bug, I would love to hear back from you.
I updated gem 'coffee-script-source', '1.8.0' in my gemfile and used bundle update in my command line. However when I run my rails server and go to the todo list I created, it still does not delete when I hit 'destroy'. In fact, I'm getting the same results as before when hitting destroy: it takes me to view my todo list. I'm not sure why. I've been trying to figure this crazy bug out for awhile now.
Bottle will do the routing and format the output, with the help of templates. The items of the list will be stored inside a SQLite database. Reading and writing the database will be done by Python code.
Templates always return a list of strings, thus there is no need to convert anything. We can save one line of code by writing return template('make_table', rows=result), which gives exactly the same result as above.
Here the action returns a 200 OK response filled with HTML content. The HTML content is provided by a template. Play templates are compiled to standard Scala functions, here as views.html.index(message: String).
This tutorial is intended to provide you with a feel of how a Pyramid webapplication is created. The tutorial is very short, and focuses on the creationof a minimal todo list application using common idioms. For brevity, thetutorial uses a "single-file" application development approach instead of themore complex (but more common) "scaffolds" described in the main Pyramiddocumentation.
This view is intended to show all open entries, according to our taskstable in the database. It uses the list.mako template available under thetemplates directory by defining it as the renderer in theview_config decorator. The results returned by the query are tuples, but weconvert them into a dictionary for easier accessibility within the template.The view function will pass a dictionary defining tasks to thelist.mako template.
When using the view_config decorator, it's important to specify aroute_name to match a defined route, and a renderer if the function isintended to render a template. The view function should then return adictionary defining the variables for the renderer to use. Our list_viewabove does both.
This template is used by the list_view view function. This templateextends the master layout.mako template by providing a listing of tasks.The loop uses the passed tasks dictionary sent from the list_viewfunction using Mako syntax. We also use the request.route_url function togenerate a URL based on a route name and its arguments instead of staticallydefining the URL path.
The #todo-input creates a local template variable that is accessible on any child or sibling element. It is then referenced in the input event binding as todoInput. Notice that this is a de-normalised name, which is required because HTML is case insensitive, a concept you might have come across from writing Angular 1 directives.
Create a new directory named imports inside the simple-todos-blaze folder. In the imports folder, create another directory with the name ui and add an App.html file inside of it with the content below:
We just created two templates, the mainContainer, which will be rendered in the body of our app, and it will show a header and a list of tasks that will render each item using the task template. Now, we need some data to present sample tasks on this page.
Adding a helper to the mainContainer template, you are able to define the array of tasks. When the app starts, the client-side entry-point will import the App.js file, which will also import the App.html template we created in the previous step.
The templating language contains a rich set of control structures to render your HTML. Here you will get an overview of the most commonly used ones.To get a detailed list of all possible structures visit: text/template
