kandi X-RAY | CalcPoints Summary
Rails is a web-application framework that includes everything needed to create database-backed web applications according to the Model-View-Control pattern. This pattern splits the view (also called the presentation) into "dumb" templates that are primarily responsible for inserting pre-built data in between HTML tags. The model contains the "smart" domain objects (such as Account, Product, Person, Post) that holds all the business logic and knows how to persist themselves to a database. The controller handles the incoming requests (such as Save New Account, Update Product, Show Post) by manipulating the model and directing data to the view. In Rails, the model is handled by what’s called an object-relational mapping layer entitled Active Record. This layer allows you to present the data from database rows as objects and embellish these data objects with business logic methods. You can read more about Active Record in link:files/vendor/rails/activerecord/README.html. The controller and view are handled by the Action Pack, which handles both layers by its two parts: Action View and Action Controller. These two layers are bundled in a single package due to their heavy interdependence. This is unlike the relationship between the Active Record and Action Pack that is much more separate. Each of these packages can be used independently outside of Rails. You can read more about Action Pack in link:files/vendor/rails/actionpack/README.html.

QUESTION
I'm trying to write a chart.js (v.2.7) plugin to show errorbars on my scatter / line plots. I managed to get the pixel positions from the chart and draw the errorbars on the canvas, but i cannot get the timing to look right. I want them to appear after the lines animate, then stay attached (& move with) if the datasets are hidden->shown.
I've tried:
- The
afterDraw
/afterDataset(s)Draw
/beforeDraw
hooks: the error bars are already on the plot before the lines animate (as in example). When hidden->shown, the error bars are in place. afterRender
/afterEvent
hook: draws them after the animation finishes, but then redraws them everytime the datasets are hidden->shown (after a pause)beforeRender
/ any earlier hooks: gives no errorbarssetTimout()
on the draw function, or at various places inside it: does nothingsleep()
before the draw function or other places: slows down the whole animation but the errorsbars are unaffected.- I couldn't find a way to invoke plugin functions after animation or get to then via the
options.animation.onComplete
Is there a way to get the errorbars to behave as in the example, but the initial appearance occurs after the line animation (with a plugin?)
...ANSWER
Answered 2019-Aug-05 at 14:33Here's what I came up with (snippet below)
The errorbars can either be fixed to the data or shown independantly, and animate in / are hidden / revealed with the data.
The plugin can add x or y axis errors, repesented as bars (with/without caps) or ovals / circles (filled or transparent).
QUESTION
I have a Laravel / Vue JS application that integrates a google map component as well as a Vuetify data-table component. The Vue instance also has a computed property that calculates the points for the Google Map, which is based upon another computed property calculated by the Vuetify data-table.
Vue Components code in view blade:
...ANSWER
Answered 2019-Jun-10 at 20:57When the vue app is created the computed properties are executed. At this point, the app doesn't have the component in the real dom (the ref keyword functions like a getElementById because prostectTable is not defined you get undefined)
In the mounted lifecycle the components are in the dom so you can access the ref. Instead of a computed property add a watcher to the refs prospectTable

i have two models "Club" class and "Match" class and it has foreign key to Club but i can not increment "won" field (or draw or lost) in "Club" class by "score_local" and "score_visitor" in "Match" class .. how can i do this
...ANSWER
Answered 2019-Apr-24 at 13:59You can't establish a relation between to fields even on the same model, but you can override the save
method in Match you could implement a signal handler to be called after every match
get saved.
QUESTION
I am making a game for an assignment where there are 2 players and each turn the player rolls 2 die. When I ask the player if they want to roll again everything goes south from there. I'm confused because even if I change my rollAgain
character to 'n'
it still plays my loop where I want it to run only if rollAgain
is 'y'
or 'Y'
. This is my first program in C, I have only programmed in Java previously. I feel like I must be checking the logical operators incorrectly in my while loop but idk what I'm doing wrong, I've looked over all the code several times now.
Here is my code:
...ANSWER
Answered 2018-Oct-08 at 07:18There are multiple classic issues in your code:
fflush(stdin);
has undefined behavior. Just remove this statement, it does not consume the pending input instdin
.scanf_s("%c", &rollAgain);
will read the pending newline in the input stream. To skip it, you can just add a space in the format string and you must test ifscanf_s
succeeded to avoid undefined behavior at end of file:

I'm having an issue with a D3 pie chart where labels are cutoff when they appear. Here's a pic:
I'm new to D3, and am not sure exactly where a fix should be. The logic for making the pie chart is 400 lines, so I made a pastebin: https://pastebin.com/32CxpeDM
Maybe the issue is in this function?
...ANSWER
Answered 2018-Aug-29 at 20:11It looks like your labels are getting transformed past the edge of your SVG boundary.
I would try to translate the label elements farther left in this function:

QUESTION
ANSWER
Answered 2018-Jan-30 at 18:49Typically this is done in a little different of a way than you seem to be thinking of it. Instead of thinking about the viewport existing somewhere in the world, you should think about the viewport being fixed and the world being transformed behind it; you don't copy part of the world to the viewport, you draw the world offset and rotated by a certain amount, and only draw the parts that are inside the viewport. Matrices are an easy and common way to represent this transformation. You may want to read more about them here.
In practice, this would just amount to changing your existing call to worldCtx.setTransform()
at the beginning of each draw frame. That link has information about how to calculate a good transform matrix, and you can find similar resources all over the place since it's pretty standard math.
In particular, you'll want to multiply a rotation and a translation matrix. Translation matrices are only possible if you use a matrix with higher-order than your coordinate space; for 2D, a 3x3 matrix, and for 3D, a 4x4 matrix. You could instead choose to just add some offset to your coordinates as you draw them, but worldCtx.setTransform
already takes a matrix with a 3rd column for putting flat offsets into.
QUESTION
I am struggling in using Parallel.For in the below code instead of for loop. Since the size of the CoefficientVector vector array is rather big, it makes sense to me only to reset the array elements value instead of creating it new for each iteration.
I try to replace the outer loop with Parallel For; and assuming each partition of the parallel for, ran by a separate thread, will have it's own copy of CoefficientVector class it therefore makes sense(?) to me to have one instance of the CoefficientVector object for each thread and reset the vector elements rather than recreating the array. I though find it hard to do this optimisation(?) on Parallel For. Could anyone help please.

I have to program a see test for an optician. So they need that the Numbers are exactly have a specific height. He has a IPad ans streams it to a TV. I know i must consider the PPI of the TV. Here is my Code :
...ANSWER
Answered 2017-Jan-02 at 03:58You need to first familiarize yourself with the different font metrics. The font size is usually (but not always) the difference between the ascender and descenders. For your purpose, the height of an uppercase letter is called the "cap height" and the height of a lowercase letter is called the "x-height".
There's no formula to translate the font size to either cap height or x-height. Their relationships different from fonts to fonts, and even variants (bold, italic, small caps, display, book) within a font.
The function below use binary search to look for a point size that matches your desired height (in inches):
