Category: Faker random number from array

A while back, if I needed dummy data for my local application environment — it involved importing a database partial of an existing site, or modifying MySQL's sakila database, or just some funky way to get data.

Laravel gave us seeding not a new concept.

Seeding lets the developer input data into the local database like it would appear on the main site. Take this scenario for example. You need to create a database with a thousand users, each user has a certain number of posts 0 - n attached to them.

You would not do this:. This is silly, nobody wants to do this a thousand time. You do not need to install this package if you are using laravel 5 or higher. After installing fakerwe can then use our seeder class to create as many users as we want.

In the run method of the UserTableSeeder class or whatever you named your seed class, do this. With the above snippet, we can create a thousand users without having to go through a lot of manual labor. Although this method saves us a lot of time and effort, it is not the most effective solution out there. When you want to create fake data for testing, you then have to copy this code and paste it in your test class. This method is not maintanable because you now have duplicate, changing a table schema would be a nightmare.

Don't forget, you should always keep your code DRY.

Model Factory lets us define a pattern used in generating fake data. TestDummy allowed developers to define a pattern for creating fake data. Model Factory became part of Laravel's features as of Laravel 5.

To use factories, we have to first define them. The first one is an identifier model FQNused to later reference the factory. Now that we have our factory defined, we can spin up fresh users anytime we want.

To use the defined factory either from your tests or seedwe use the factory function provided by laravel. This creates a single user. To create many users — just pass a second parameter to the factory function. If you want to override some of the default values of your model, you may pass an array of values to the create method. Only the specified values will change — while the rest of the values remain set to their default values as specified by the factory.

Sometimes we may not want to save the data created to the database. For that we use the make method on the factory object instead of create. Just like we did with the create method, we can also overwrite attributes of the method also. It works on the same principle as the create method.

A model can be of different types; we can configure a model factory to use many types. The first parameter is the base model, the second parameter is a type and the third parameter is a closure that generates data. To use this factory created using defineAs method, we can change the second argument to the factory from number of posts to the new factory identifier. A basic User model usually has relations with other models.

For example a user can have posts, if we wanted to make a user have posts using model factories, we can do this.We mark a TypeScript class as injectable using the Injectable decorator which also takes a providedIn property to specify the module where the service should be provided. By default, this is root which is simply an alias for AppModule.

Since our tutorial is about frontend web development with Angular 9, we either need a third-party REST API which is available from public servers on the web or better, we can use tools like json-server to generate fully working backend APIs with fake data. Head back to your command-line interface and install Faker.

At the time of building this example, faker v4. We first imported faker, and next we defined an object with one empty array for products. Next, we entered a for loop to create fake entries using faker methods like faker.

Check all the available methods. Finally, we converted the database object to a string and logged it to standard output. Next, add the init-api and serve-api scripts to the package.

Congratulations, you are ready for the next step! Next, we need to use this service in our home component. We imported and injected ApiService. Next, we iterated over the products array and used a Material card to display the namepricequantitydescription and image of each product.In this tutorial, we will see how to generate random hexadecimal color code in Java. Colors are specified using hexadecimal values. It is in the form of a hex triplet, which represents three separate values specifying the levels of the component colors RGB.

Therefore, we call nextInt method on that instance to generate random number. The parameter passed to this function is the maximum permissible value of the generated number Excluding the limit. The maximum value in our case is ffffff.

SamuelMarks but it's ugly and awkward. I looked lo and fro in the API for this feature, and came here since I didn't find anything.

Of course, the feature is trivial, but would be an interesting one Would result in an array from 1 to 5 elements, containing the given objects. In the first case, each array element is the result of the function call.

In the second case, each array element is a clone of the specified object.

To me, "ugly and awkward" APIs are those which bloat or take away from the core functionality required. If you want a more expressive API, feel free to create a new library which takes in faker as a dependency.

Lot's of developers do this and it generally works out great.

It generates a lot of blocks of successive numbers So, if you wantyou can multiple it by 40, the highest the result can ever be is what you're multiplying by.

Sequences of random items often contain blocks of successive numbers, see the Gambler's Fallacy. For example:. Since the range of numbers is constrained, I'd say the best thing to do is generate the array, fill it with numbers zero through 39 in orderthen shuffle it.

This above is the traditional way of doing it but I second Pointy and Phrogz if you want to avoid duplicates in your array without having to do expensive computation. Values in arrays is total random, so when you will be use this snippets, it will different. Note that this solution will only work in modern browsers that support these ES6 features: arrow functions and Array.

I needed something a bit different than what these solutions gave, in that I needed to create an array with a number of distinct random numbers held to a specified range. Below is my solution. I would have preferred to not create a loop that has the possibility to end up with a lot of unnecessary calls if your count, and range are high and are close to the same number but this is the best I could come up with.

I guess this method will solve the issue with the probabilities, only limited by random numbers generator. A little late to the party, but I use randojs.

Fake phone numbers randomly generated by Fake Number are unallocated numbers that telephony companies cannot assign to Richmond customers under current legislation.

This is to protect residents against the potential influx of phone calls that they may receive should their telephone numbers appear in a movie or film. Were you to make up a random Richmond phone number yourself, there is a high chance of your number ending up being valid.

If you're still not convinced about how we can help, you should read up on the makers of film 'Bruce Almighty' using as a number to call God, which resulted in nuisance calls across many areas. Please note that the use of any fake telephone numbers generated by Fake Number does not imply that the resulting Richmond number has been allocated.

It should also be remembered that whilst these random phone numbers will not be assigned for use by telephony companies in the foreseeable future, there is no guarantee that this situation will remain unchanged forever. Ultimately, ensuring that there is sufficient numbering capacity available to meet future requirements for 'real' Richmond telephony purposes is likely to be of greater priority.
