How do you put the name Yii2 instead of the number? GridView

Bogopo last edited by

Available GridViewbut the categories are numerical. How do you remove names from another table - categories instead of those figures for Category_id-Title? It's very difficult to give Yii2.

What do I have to write in the code? I tried differently, and http://www.elisdn.ru/blog/76/seo-service-on-yii2-admin-and-sef I took, and http://nix-tips.ru/yii2-razbiraemsya-s-gridview.html ♪ But it ended with mistakes. Thank you for your help!

[
    'attribute' => 'category_id',
    'filter' => Html::activeDropDownList(
          $searchModel,
          'category_id',
          ArrayHelper::map(Category::find()->all(), 'id', 'name'),
          ['class' => 'form-control']
     ),
     'value' => 'category.name',
]

This method still works, don't pay attention to the filter. 'value' => 'category.name'♪ I don't know if it's more beautiful than the previous one, but I'm new. Works like that, tells me who's old at what's the difference?

You can either create a list and count its items (this if you will also need to store the years), or put an accountant as @DanteS tells you.Accountant:date1 = int(input("Tell me one date: ")) date2 = int(input("Tell me another date: ")) counter = 0 # Inicias el contador a 0 if date1 < date2: print ("Leap years between", date1, "and", date2, "are: ") while date1 <= date2: if date1 % 4 ==0 and date1 % 100 !=0: counter += 1 # En vez de imprimir añades 1 al contador if date1 % 100==0 and date1 % 400 ==0: counter += 1 # En vez de imprimir añades 1 al contador date1 += 1 print(counter) Store the years on a list:date1 = int ( input( "Tell me one date: ")) date2 = int(input("Tell me another date: ")) leap_years = [] # Creas una lista vacía if date1 < date2: print ("Leap years between", date1, "and", date2, "are: ") while date1 <= date2: if date1 % 4 ==0 and date1 % 100 !=0: leap_years.append(date1) # Añades el año a la lista if date1 % 100==0 and date1 % 400 ==0: leap_years.append(date1) # Añades el año a la lista date1 += 1 print(leap_years, len(leap_years)) This besides returning the list of years leap_years, returns you how many years there are on that list len(leap_years).Clarification on your codeYou can also remove the part you check date1 % 100==0 since you force him to fulfill date1 % 400==0 And if he fulfills the latter, he will do the first forcibly. So you could leave that line like that. if date1 % 400 ==0:And if you want to reduce it even more so as not to repeat the increase to the counter (I only put the part of the counter while(c):while date1 <= date2: if date1 % 4 == 0 and date1 % 100 != 0 or date1 % 400 == 0: counter += 1 date1 += 1

You can do something like this, if it serves you. .<?php $_id = 1; $id_encoded = base64_encode($_id); // resultado: MQ== ?> <a href="advanceplus.php?id=<?= $id_encoded?>">ok</a> <?php //resultado link: advanceplus.php?id=MQ== $id_decoded = base64_decode($GET['id']); //id identificado 1 ?>

Due to the symptoms of error it seems that you have not obtained composer dependencies, since the file vendor/autoload.php is generated by composer at the time of running composer install or composer update.

There's probably nuances, but most of them work:function countOfNumbers(arr) { return arr.filter(item => Number.isFinite(item)).length; } alert(countOfNumbers(['7', 2.5, 'a', 0, true, 'b', 1, 'c', Infinity, NaN, -Infinity, null]))

Depending on the PHPixie version, there are the following ways:2.xAssuming you already have a model Person You can just put the name of the table in the field. $table:class Person extends \PHPixie\ORM\Model { public $table = 'person'; } See documentation: https://phpixie.com/2.x/orm.html 3.xYou can redesign the default value in the configuration file:<?php // bundles/app/assets/config/orm.php return array( 'models' => array( 'person' => array( 'table'=> 'persons', ), ); ); See documentation: https://phpixie.com/components/orm.html#configuration

First and foremost, STOP USING MD5! It is a broken hash function, and its been broken for many years. Also you have to use an hmac, calling md5 directly is vulnerable to a length extension attack. Testing the ip address is problematic because this value can change if the user is behind a load balancer, which is commonly used by universes and corporate offices. The attacker will always have the user-agent, and this value is very easy to brute force. Testing this value is in no way shape or form a "security measure". Its a lot like having a variable is_attacker=no and making sure this value is "no", which is A JOKE! When I see a programmer doing this I smell blood, if they actually think this helps improve security then they have likely made other mistakes. Set your php session configurations as follows: session.cookie_httponly = 1 (helps mitigate xss) session.session.use_only_cookies = 1 (prevents session fixation) session.entropy_file = "/dev/urandom" (better entropy source) session.cookie_lifetime = 0 (smaller exploitation window for xss/csrf/clickjacking...) session.cookie_secure = 1 (owasp a9 violations)

Try regulars:import re t = 'Tny6anxayna = 104 nognucunkos §—-29 noanucok' p = re.compile("(\d*) ") m = p.findall(t) m = ['', '', '104', '', '29'] ls = [] for i in m: if i != "": ls.append(i) print(ls) It may be possible to make a regular presentation better so that there are no gaps that can be removed from the outer structure if this is a quick version.

If you need to introduce numbers with commas, etc., this is the example of the code:for (int i = 0; i < n; ) { //Проверяем было ли введено число if (scanf("%d", &number[i]) == 1) //Если да то увеличиваем кол-во введенных чисел на 1 и считаем сумму concatenation = concatenation + number[i++]; //если нет то освобождаем буфер от неправильно введенного символа else getchar(); } The code will be used until the user enters n Chisel.Read the details. scanf You can. http://www.c-cpp.ru/content/scanf or https://en.cppreference.com/w/c/io/fscanf I'll give you a full code for example:#include <stdio.h> #include <string.h> #include <stdbool.h> #include <locale.h> int main() { char* locale = setlocale(LC_ALL, ""); int number[3]; int concatenation = 0; int n; printf("Введите кол-во элементов: "); scanf("%d", &n); printf("Введите %d элементов: ", n); for (int i = 0; i < n; ) { //Проверяем было ли введено число if (scanf("%d", &number[i]) == 1) //Если да то увеличиваем кол-во введенных чисел на 1 и считаем сумму concatenation = concatenation + number[i++]; //если нет то освобождаем буфер от неправильно введенного символа else getchar(); } getchar(); printf("Итоговая сумма: %d\n", concatenation); printf("Введите любой сивол и получите ошибку, но если введете 'q' то произойдет выход из программы\n"); do { printf("Нажмите [q] для выхода..."); char ch = getchar(); char sch = getchar(); //Чтобы не повторялось сообщение об ошибке //Нужно очистить буфер от символа новой строки //и проверить если пользователь сначала ввел символ новой строки а потом уже //например q if (ch != 'q' && sch != 'q') printf("Ошибка.\r\n"); else break; } while (true); return 0; } Programme result:

tl/dr: If you have a read-only endpoint that only serves public data, then don't bother to try to secure it further. It's not worth the time, and is impossible to do anyway. You have a few misunderstandings here that are worth addressing. It's not about blocking connections from outside your server You're trying to make it so that your API endpoints only respond to your SPA. However, that is not the same thing as limiting connections only to your server. The reason is because your react app doesn't run on your server - it runs in the user's browser. Your server sends the React app to the client, which runs in their browser. As a result the API calls come not from your server but from your users' web browsers, potentially located around the world. Of course the browser will helpfully send up the Origin header, letting you know that the request is being made on behalf of JavaScript that was hosted on your domain. As you note though this definitely can be spoofed, as any non-browser client can easily send up whatever Origin they want. In fact, every single aspect of the HTTP request can be spoofed by the client. Therefore you want to block requests not coming from your app Unfortunately for you this is quite literally impossible. You can take steps to make it harder, but since the app runs on the client's machine, a sufficiently dedicated adversary would be able to reverse engineer any and all parts of it until they learn how your protection works and could then reproduce it wherever they want. In essence, you are asking how to implement DRM. While you certainly could try to implement some steps to make it harder for someone to make API requests to your server from outside of your app, in your particular use case it is highly unlikely that this would be worth the effort (especially for a demo app). For broader context, if I were looking at a demo app of a candidate and saw that they implemented some ad-hoc DRM solution to try to keep people out of an otherwise anonymous endpoint, then I personally wouldn't consider this a good thing. The most important part of security is learning to balance the risks and benefits, since any security measure inherently has some cost (if only the cost to develop it). In particular any time spent implementing security features takes time away from feature development. Most companies screw up by spending no time on security and more time on features, but there is an opposite side of that coin too. Taking time to try to secure an endpoint in a way that cannot actually be done effectively is a poor way to spend time when there are always more features to implement! Note, I don't say this to criticize your question or your thought process (which demonstrate a lot of forward thinking!), but rather to help you understand the broader "landscape" that you find yourself in. Summary In short, if you have a read-only endpoint that only serves public data, then don't bother to try to secure it further. It's not worth the time, and is impossible to do anyway.

You must check inside your file AndroidManifest.xml from where it takes the label that assigns the name, regularly it is taken from strings.xml with entrance app_name:<application android:label="@string/app_name" but in your case you are possibly taking the name of another entry or file and even this defined directly the name of the application: <application android:label="mi aplicacion"
