👨‍👩‍👧‍👦Team work summary and reflection

Team work issues

• The communication between the front and back end members is insufficient, the workload is unbalanced, and the potential of each member is not fully utilized, which leads to the slow progress of the project
• Lack of solid professional knowledge, such as not proficient in the use of front-end and back-end, not smooth in the use of Github team collaboration function, and difficult project progress

Solution

• In view of question 1, we will strengthen the communication between the teams, summarize the work situation of the day every day, and arrange the tasks of the next day according to this situation to ensure the smooth progress of the project.
• In view of question 2, we decided to start from basic learning, and the specific division of labor will be reflected in the personnel arrangement.

What we have done:

• Solved how https://img-community.csdnimg.cn/images/42fed9fe22514de7bc3a6372eb0e5c24.png "#left")
  to keep the plane in the same proportion position in different models (found many methods and finally used margin to solve)
• The current time is displayed on the home page
• Realizes the navigation bar setting, and presses will have the different icon effect
• Solved the search bar page design and search bar establishment
• How to get user information function solved

Open question:

• New users interested in the tag although good, but behind the guess you like weigh is not really implemented, that is to say, click on the system does not allow you to select the tag of the article.
• How to collect articles and display them one by one in the favorites page has not been implemented; If possible, we want to make it show how many people have collected the article
• All the contents of the search page are ready, but the operation of clicking on the search page to jump to the web page is not implemented

💾Cloud development back end


Code 1: Call the cloud function to update the number

  //调用云函数更新数量
      wx.cloud.callFunction({
        name:"update1119",
        data:{
          id:id,
          price:parseInt(price)
        }
      }).then(res => {
        console.log('调用云函数成功', res)
        this.getDetail()
      }).catch(res => {
        console.log('调用云函数失败', res)
      })
    }
  },

      

Code 2: Local applets call the database directly to update the number

update() {
    console.log('新的数量', price)
    if (price == '') {
      wx.showToast({
        icon: 'none',
        title: '空',
      })
    } else {
      本地小程序直接调用数据库更新数量
      wx.cloud.database().collection('goods')
        .doc(id)
        .update({
          data: {
            price: price
          }
        })
        .then(res => {
          console.log('更新成功', res)
          this.getDetail()
        })
        .catch(res => {
          console.log('更新失败', res)
        })

Code 3: Cloud function call

// 云函数入口文件
const cloud = require('wx-server-sdk')
cloud.init({
  env:cloud.DYNAMIC_CURRENT_ENV
})

// 云函数入口函数
exports.main = async (event, context) => {
  return cloud.database().collection('goods')
  .doc(event.id)
  .update({
    data: {
      price: event.price
    }
  })
}

What we have done

• Learn the use of cloud functions, realize the cloud database to add, delete, change, check, screehttps://img-community.csdnimg.cn/images/8b1f0a12cd3c4d1d89d8846404af096a.png "#left")
  ning, capacity expansion and other functions.

Open question

• The crawler data cannot be written to the cloud database, so it cannot be called further
• Local configuration of mysql is a knowledge blind area, server port open cannot be linked

🤏Process experience for each employee

👨‍🎓Leader: Xiaolong Han__ Miracle：

Just like the previous LABS, this new one is also a new challenge. The teacher encouraged us to jump out of the comfort zone, so that I could have completely different experience and harvest in each LAB. At the same time, the team LAB is a bigger challenge for me, the leader, and there are more problems to solve. Thanks to my teammates, the five people worked together to find and solve the problems, and finally we submitted a work that we didn't want to see. The end of this LAB should also signal the end of all LABS. I will remember the feelings of each experiment and urge me to learn not to give up and persevere.

👩‍🎓Teammate 1: Yongquan Wang __ Kerio：

In order to realize the backend, we made all kinds of attempts, as long as we thought possible to achieve the way to learn, but the result seems not so direct to achieve the effect we want. Although the results may not be that rich, I have learned a lot about the approaches and characteristics of back-end development through this opportunity, and grasped the applicable scenarios and constraints in practice. More importantly, I have cultivated the ability to find effective solutions to problems I encounter. I should be more prepared for future back-end development

👨‍✈️Teammate 2: Jiatong Zhang __ Allen：

In this Alpha Sprint project, we almost started from scratch. In the team, I was responsible for the data call part. In the process of trying to produce, I learned many aspects of knowledge successively, and finally chose wechat cloud development. At the beginning, I had no direction. I felt that I had learned a lot of new knowledge, but I didn't know which one could be used. Until I finally decided to use wechat cloud development, I had no direction. Although this project did not fully realize the function we set initially, I benefited a lot from the learning process and greatly exercised my learning ability.

👨‍⚖️Teammate 3: Shuoyuan Chen __ Dio：

Small programs really have immeasurable possibilities and challenges. When I do front-end design, I can spend a lot of time trying to get a simple effect. Maybe that effect could have been done with a single line of code, but it would have taken me hours to find that line of code. We seek solutions through various methods, such as CSDN, Github, Baidu search, etc. As long as there is a possible solution, we will read the article patiently. During this week, I saw myself becoming proficient in operation, the team struggling all night for the project, and everyone suffering and crying, but challenging the limit for a common goal. That's probably what the Alpha sprint is all about

👩‍⚖️Teammate 4: Xiaotong Shao：

Through the team cooperation of this project, I realized that team cooperation can often stimulate the incredible potential of the group, and the results of collective cooperation can often exceed the sum of individual achievements of the members. Is the so-called "concentric mountain into jade, together soil into gold." The victory of the Red Army's Long March was a miracle of the Chinese revolution and even the world's military. The red Army soldiers who created this miracle and the whole Red Army team are an excellent team, which not only got out of the difficult situation but also laid the foundation for the victory of the revolution under their joint cooperation. Therefore, success requires the spirit of overcoming difficulties, but also the resultant force of unity and cooperation.
