configuration management – Attempt to create a non-existent field body on an entity type node – Drupal 8.6.7

I have recently started to encounter this error when activating a module or configuration of the content type management zone. This was not a problem before.

Drupal Core Field FieldException: Try to create a field body that does not exist on the entity type node. in Drupal field Entity FieldConfig-> getFieldStorageDefinition () (line 315 of /web/core/modules/field/src/Entity/FieldConfig.php).

Could you please guide me on how can I get this missing piece repaired.
Any help would be greatly appreciated. Thank you!

views – hook_views_data_alter to turn the contents of the body field of text titles into "bold"

What would a hook_views_data_alter look like to turn body text content into bold.

It means adding an element of html code to the body's content. For example:

"First name: is simply a fake text of the industry of printing and composition. Lorem Ipsum is the standard dummy text of the industry since the 1500s. Last name: when an unknown printer took a galley of type and scrambled it to make a typical notebook. He has not only survived five centuries. "Third Name: Also the jump in the electronic composition, remaining essentially.

Any help would be appreciated.

I want to know how to make a vegetarian sprinkler

Learn more about the structure of Sprinkler Sprinkler

For those who work in the fire prevention and fire room, it is no stranger to fire sprinkler heads. But for many people, they are very unfamiliar with this product and do not know how this device is manufactured, Buy Direction of sprinkler spray head Where to ensure a genuine? So, to address these concerns below, we will have a useful sharing for you.

1. What sprinkler sprinkler head sprinkler?

First of all, we need to know what the sprinkler sprinkler is. As a result, this unit is the first type of water that will radiate on burned areas and fire. Currently, many types of nozzles are designed for fires with their own characteristics. Once designed, the nozzle type will be established based on the structure of the nozzle body.

What is the sprinkler head

2. Learn sprinkler sprinkler structure

Although there are many sprinkler heads. But in terms of construction, these types of nozzles will include the following parts.

2.1 Watering nozzles

The nozzle body is one of the important parts of Sprinkler nozzles. With this body will contribute to the structure of the nozzle. Since then, the nozzle can withstand high pressure during spraying and spraying activities.

The body of the nozzle on top has a thermal sensor as well as a water tensioner. With this block blocking the water on the body of the nozzle, it is necessary to adjust the appropriate water spray direction.

In order to ensure durability and high resistance to pressure, the material imparts to the body of the nozzle good metals such as copper, chrome plating … with good resistance to rust.

2.2 Heat sensor parts

As mentioned above, the thermal sensor is equipped above the body of the nozzle, which consists of a glass jar and inside the glass jar contains the cashier. This unit will automatically perform the operation when the temperature is above the allowed level to handle the fire quickly and efficiently.

At normal temperature, the role of the heat sensor is to maintain the cover to ensure watertightness. If the temperature is reached, this sensor will function to release water and play the role of the nozzle of the nozzle.

2.3. Lock button

The next part of Sprinkler Fire sprinkler head structure is the lock button. As its name indicates, this part aims to ensure that the water stays inside and not to run away. In addition, the button works smoothly with the heat sensor to prevent water splashing.

When a problem is detected, this block will be automatically deleted. From then on, water spray will spray water to extinguish the fire.

2.4. Instruction Sheet

The next part of the sprinkler nozzle structure is the instruction sheet. This guide will be installed in the position on the nozzles and directly in front of the stop button.

The role of the main guideline is to split the water spray so that water can spread widely over the fire zone, thus ensuring the presence of a fire in an extended area. The direction of the nozzles will be determined by the guide plate.

3. Address provides sprinkler sprinkler

Currently, the purchase and possession of a sprinkler are widely chosen to ensure the rapid extinction of a fire in the event of an incident. So many people want to know the price list of sprinkler nozzles to have a financial preparation plan as well as to select suitable products. Many sprinkler sprinklers have sprung up on the market, such as sprinklers head up, sprinklers sprinklers, automatic sprinkler heads, horizontal sprinklers. In addition, understanding the spray nozzle price list also allows customers to purchase standard products, avoiding damage.

For peace of mind when choosing genuine, quality sprinkler nozzles as well as to ensure a reasonable price, you must learn how to choose the address provided by the prestigious Sprinkler Sprinkler Sprinkler. And now, An Phat Technology & Trade Development Co., Ltd. is located at 74, T8 Street, Tay Thanh Street, Tan Phu District, Ho Chi Minh City.

nt.number theory – How did Gauss find the units of the cubic body $ Q[n^{1/3}]$?

I recently read an article on jstor "Gauss and the early development of algebraic numbers", which describes the genesis of Gauss's ideas on the foundations of the algebraic theory of numbers, among other useful information, he mentions a certain ternary cubic form that Gauss studied in 1808 to try to understand the principles under higher rates of reciprocity (cubic reciprocity in this case).

The particular form is:
$$ F (x, y, z) = x ^ 3 + ny ^ 3 + n ^ 2z ^ 3 – 3nxyz $$ and Gauss attempted to find (rational) solutions to the Diophantine equation $ F (x, y, z) = $ 1. As the article explains, this particular form appears as the norm of the number $ x + vy + v ^ 2z $ (or $ v = n ^ {1/3} $) in the pure cubic field created by joining $ v $ the field of rationals. Since Gauss wanted to know where this expression was equal to 1, this investigation can be interpreted as an attempt to find the units (norm 1 numbers) in this cubic field. Gauss then recorded the units for some values ​​of n and, in some cases, presented the fundamental unit.

I have not found enough information about this Gaussian investigation. So now, to my questions:

  • What was the Gauss procedure? And how does this relate to Gauss's other investigations in the algebraic theory of numbers?

  • Does this have anything to do with the Dirichlet Unity Theorem?? I ask the question because this article says that the Gaussian investigation was "a step in the progression of Lagrange to Dirichlet, the latter having developed in 1842-1846 the general theory of algebraic units …".

A word about the shutter ratings

The shutter activation counts are calculated in the same way as the "average time to failure" values ​​of the hard disk. Practically, it is impossible to physically test a hard drive under normal use until it physically dies enough time to obtain statistically useful results. If a company tried to do it, it would spend about 11 years testing hard drives requiring a MTBF of 100,000 hours. Instead, they perform an accelerated test on a large number of hard disk samples by subjecting them to high stress, and then compute an average and statistically useful MTBF based on the failure times of all the test disks. .

The number of shutter operations is calculated in the same way. A large number of blanks from a batch are tested continuously until failure and the average failure rate of all the blanks in the pack is over. samples is calculated. A trigger planned for 100,000 actuations came from a batch that had failed at around 100,000 actuations during testing, which is a pretty average number for most entry-level and midrange DSLRs . A shutter designed for 300,000 actuations came from a particularly good lot or from a lot manufactured with stricter specifications.

Nominal value

You must take a shutter release index at its face value. First, they are calculated to be statistically accurate. While there are always doubts in any set of statistics and you may end up with a trigger that lasts twice as long or twice as long as its rated life, they must generally last as long as they are valued. Secondly, statistical evaluations such as the MTBF or the number of shutter actuations tend to be pessimistic rather than optimistic. I guess it eases the legal pressure of those who like to sue for insignificant things and gives more weight to the rating.

Use and environment

Your personal experience with the life of the shutter can depend on how you use it. If you're using an entry-level digital SLR for professional use, with burst sports or wildlife shooting in harsh, dirty or wet environments, you'll probably still get less d & # 39; 39, use a shutter than what was planned so far. On the other hand, if you use a high quality professional camera with a gentler use and take very good care of your equipment, the shutter could last much longer than its face value. A shutter designed for 300,000 actuations (that is, those used in a Canon EOS-1Ds MkIII series body) is not only manufactured to higher specifications, but is also tested by continually activating a sample until the shutter goes down. In the worst case, you can continuously activate a shutter for a few hours at a time, then the camera is stored until its next use.

If you plan to buy a camera with a lower subscript, say 20,000, make sure you understand how you intend to use it. I bought my first camera, a Canon Rebel XSi (450D) about 18 months ago. I've used 5,000 shots in the first two months and I've already received over 10,000 shots. I expect this organism to last at least a few years, and if it only had 20,000 triggers, it would probably be by the end of the year. . As far as most DSLRs are concerned, I think the lowest shutter index is 100,000, which is generally not a problem. I can not say as much for the P & S cameras, but I would say that a trigger speed of 5000 does not go very far at all and a reduction of 20,000 actuations would be more reasonable. This assumes that it is equipped with a shutter … many P & S cameras use electronic shutters.

javascript – Lambda does not return the body with an http response to API Gateway

The response only very well indicates Lambda when I run a very simple query with the module js js, but when I call the function via API Gateway, the body is returned empty even after putting the result on the body of the answer.

answer = {
"statusCode": 200,
"body": JSON.stringify (results),
"isBase64Encoded": false
callback (null, response, connection.end ());

I draw from this:

"statusCode": 200,
"body": "[]"
"isBase64Encoded": false

on API Gateway but it shows that

"statusCode": 200,
"body": "[{"id":15,"username":"3FWF34fWF","password":"sha1$02f44ad2$1$c81a28b3217a4fb777850e85dbdfa088ab44266d","email":"3514t34fg","activated":0,"name":"fEEFEFAE4"}]"
"isBase64Encoded": false

when I test the code on lambda.

Any help would be incredible. I am able to give more information at any time.

vba – Visual Basic Application for Body Mass Index (BMI)

The body mass index of a person is a measure of body fat based on height and weight. In typical US units, it is determined by: IMC = 703 (W / h 2) where "W" is the weight in pounds and "h" is the height in inches. Write a Visual Basic application subroutine that calculates the BMI. Use the explicit option. For input, the subroutine prompts users to enter their weight and size (use the InputBox function). The program then calculates the BMI rounded to the nearest tenth. To exit, the program displays the message using the MsgBox function: "The" BMI "is XX". where XX is the value of IMC. Determine the BMI of a 68-year-old who weighs 162 pounds. Tip: To round to the nearest tenth, use the "Application round" function.

portrait – What type of lens filter passes between the lens and the body and contains flakes of metal?

About 20 years ago, when I started in photography, I was in a portrait studio. He showed me some of his equipment. One thing that I found interesting is a set of square filters that he used. They were made of solid glass, about 1/8 "to 1/4" thick and seemed to have glitter of metal at different depths in the glass. What was strange was that the filters were inserted between the lens and the camera body rather than being mounted in front of the lens. If I remember correctly, they produced a brilliant and soothing effect that videographers called the effect "Barbara Walters".

How are these filters called? I have never seen anything like it since, even though I do not do a lot of portraits.
